How many dialects are spoken by the Mongol?

Mongols in Inner Mongolia speak Mongolian dialects such as Chakhar, Xilingol, Baarin, Khorchin and Kharchin Mongolian and, depending on definition and analysis, further dialects or closely related independent Central Mongolic languages such as Ordos, Khamnigan, Barghu Buryat and the arguably Oirat dialect Alasha. The standard pronunciation of Mongolian in China is based on the Chakhar dialect of the Plain Blue Banner, located in central Inner Mongolia, while the grammar is based on all Southern Mongolian dialects. This is different from the Mongolian state, where the standard pronunciation is based on the closely related Khalkha dialect. There are a number of independent languages spoken in Hulunbuir such as the somewhat more distant Mongolic language Dagur and the Tungusic language Evenki. Officially, even the Evenki dialect Oroqin is considered a language.

Inner Mongolia

Inner Mongolia or Nei Mongol (Mongolian: "Öbür Monggol", "Övör Mongol" ; ), officially the Inner Mongolia Autonomous Region or Nei Mongol Autonomous Region (NMAR), is one of the autonomous regions of the People's Republic of China, located in the north of the country. Its border includes most of the length of China's border with Mongolia (Dornogovi, Sükhbaatar, Ömnögovi, Bayankhongor, Govi-Altai, Dornod Provinces). The rest of the Sino–Mongolian border coincides with part of the international border of the Xinjiang autonomous region and the entirety of the international border of Gansu province and a small section of China's border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, and Ordos.

The Autonomous Region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei and Xing'an, along with the northern parts of Gansu and Ningxia.

Its area makes it the third largest Chinese subdivision, constituting approximately and 12% of China's total land area. It recorded a population of 24,706,321 in the 2010 census, accounting for 1.84% of Mainland China's total population. Inner Mongolia is the country's 23rd most populous province-level division. The majority of the population in the region are Han Chinese, with a sizeable titular Mongol minority. The official languages are Mandarin and Mongolian, the latter of which is written in the traditional Mongolian script, as opposed to the Mongolian Cyrillic alphabet, which is used in the state of Mongolia (formerly often described in the West as "Outer Mongolia").

In Chinese, the region is known as "Inner Mongolia", where the terms of "Inner/Outer" are derived from Manchu "dorgi"/"tulergi" (cf. Mongolian "dotugadu"/"gadagadu"). Inner Mongolia is distinct from Outer Mongolia, which was a term used by the Republic of China and previous governments to refer to what is now the independent state of Mongolia plus the Republic of Tuva in Russia. The term Inner (Nei) referred to the Nei Fan (Inner Tributary), i.e. those descendants of Genghis Khan who granted the title khan (king) in Ming and Qing dynasties and lived in part of southern part of Mongolia. In Mongolian, the region was called "Dotugadu monggol" during Qing rule and was renamed into "Öbür Monggol" in 1947, "öbür" meaning the southern side of a mountain, while the Chinese term "Nei Menggu" was retained. In recent years, some Mongols (mainly those who support independence from China) began to call Inner Mongolia "Nan" () "Menggu", literally "South Mongolia", and with it came the change of English translation from Inner Mongolia to Southern Mongolia.

Much of what is known about the history of Greater Mongolia, including Inner Mongolia, is known through Chinese chronicles and historians. Before the rise of the Mongols in the 13th century, what is now central and western Inner Mongolia, especially the Hetao region, alternated in control between Chinese agriculturalists in the south and Xiongnu, Xianbei, Khitan, Jurchen, Tujue, and nomadic Mongol of the north. The historical narrative of what is now Eastern Inner Mongolia mostly consists of alternations between different Tungusic and Mongol tribes, rather than the struggle between nomads and Chinese agriculturalists.

Slab Grave cultural monuments are found in northern, central and eastern Mongolia, Inner Mongolia, north-western China, southern, central-eastern and southern Baikal territory. Mongolian scholars prove that this culture related to the Proto-Mongols.

During the Zhou dynasty, central and western Inner Mongolia (the Hetao region and surrounding areas) were inhabited by nomadic peoples such as the Loufan, Linhu, and Dí, while eastern Inner Mongolia was inhabited by the Donghu. During the Warring States period, King Wuling (340–295 BC) of the state of Zhao based in what is now Hebei and Shanxi provinces pursued an expansionist policy towards the region. After destroying the Dí state of Zhongshan in what is now Hebei province, he defeated the Linhu and Loufan and created the commandery of Yunzhong near modern Hohhot. King Wuling of Zhao also built a long wall stretching through the Hetao region. After Qin Shihuang created the first unified Chinese empire in 221 BC, he sent the general Meng Tian to drive the Xiongnu from the region, and incorporated the old Zhao wall into the Qin dynasty Great Wall of China. He also maintained two commanderies in the region: Jiuyuan and Yunzhong, and moved 30,000 households there to solidify the region. After the Qin dynasty collapsed in 206 BC, these efforts were abandoned.

During the Western Han dynasty, Emperor Wu sent the general Wei Qing to reconquer the Hetao region from the Xiongnu in 127 BC. After the conquest, Emperor Wu continued the policy of building settlements in Hetao to defend against the Xiong-Nu. In that same year he established the commanderies of Shuofang and Wuyuan in Hetao. At the same time, what is now eastern Inner Mongolia was controlled by the Xianbei, who would later on eclipse the Xiongnu in power and influence.

During the Eastern Han dynasty (25–220 AD), Xiongnu who surrendered to the Han dynasty began to be settled in Hetao, and intermingled with the Han immigrants in the area. Later on during the Western Jin dynasty, it was a Xiongnu noble from Hetao, Liu Yuan, who established the Han Zhao kingdom in the region, thereby beginning the Sixteen Kingdoms period that saw the disintegration of northern China under a variety of Han and non-Han (including Xiongnu and Xianbei) regimes.

The Sui dynasty (581–618) and Tang dynasty (618–907) re-established a unified Chinese empire, and like their predecessors, they conquered and settled people into Hetao, though once again these efforts were aborted when the Tang empire began to collapse. Hetao (along with the rest of what now consists Inner Mongolia) was then taken over by the Khitan Empire (Liao dynasty), founded by the Khitans, a nomadic people originally from what is now the southern part of Manchuria and eastern Inner Mongolia. They were followed by the Western Xia of the Tanguts, who took control of what is now the western part of Inner Mongolia (including western Hetao). The Khitans were later replaced by the Jurchens, precursors to the modern Manchus, who established the Jin dynasty over Manchuria and northern China.

After Genghis Khan unified the Mongol tribes in 1206 and founded the Mongol Empire, the Tangut Western Xia empire was ultimately conquered in 1227, and the Jurchen Jin dynasty fell in 1234. In 1271, Kublai Khan, the grandson of Genghis Khan established the Yuan dynasty. Kublai Khan's summer capital Shangdu (aka Xanadu) was located near present-day Dolonnor. During that time Ongud and Khunggirad peoples dominated the area of what is now Inner Mongolia. After the Yuan dynasty was overthrown by the Han-led Ming dynasty in 1368, the Ming captured parts of Inner Mongolia including Shangdu and Yingchang. The Ming rebuilt the Great Wall of China at its present location, which roughly follows the southern border of the modern Inner Mongolia Autonomous Region (though it deviates significantly at the Hebei-Inner Mongolia border). The Ming established the Three Guards composed of the Mongols there. Soon after the Tumu incident in 1449, when the Oirat ruler Esen taishi captured the Chinese emperor, Mongols flooded south from Outer Mongolia to Inner Mongolia. Thus from then on until 1635, Inner Mongolia was the political and cultural center of the Mongols during the Northern Yuan dynasty.

The eastern Mongol tribes near and in Manchuria, particularly the Khorchin and Southern Khalkha in today's Inner Mongolia intermarried, formed alliances with, and fought against the Jurchen tribes until Nurhaci, the founder of the new Jin dynasty, consolidated his control over all groups in the area in 1593. The Manchus gained far-reaching control of the Inner Mongolian tribes in 1635, when Ligden Khan's son surrendered the Chakhar Mongol tribes to the Manchus. The Manchus subsequently invaded Ming China in 1644, bringing it under the control of their newly established Qing dynasty. Under the Qing dynasty (1636–1912), Greater Mongolia was administered in a different way for each region:

The Inner Mongolian Chahar leader Ligdan Khan, a descendant of Genghis Khan, opposed and fought against the Qing until he died of smallpox in 1634. Thereafter, the Inner Mongols under his son Ejei Khan surrendered to the Qing and was given the title of Prince (), and Inner Mongolian nobility became closely tied to the Qing royal family and intermarried with them extensively. Ejei Khan died in 1661 and was succeeded by his brother Abunai. After Abunai showed disaffection with Manchu Qing rule, he was placed under house arrest in 1669 in Shenyang and the Kangxi Emperor gave his title to his son Borni. Abunai then bid his time and then he and his brother Lubuzung revolted against the Qing in 1675 during the Revolt of the Three Feudatories, with 3,000 Chahar Mongol followers joining in on the revolt. The revolt was put down within two months, the Qing then crushed the rebels in a battle on April 20, 1675, killing Abunai and all his followers. Their title was abolished, all Chahar Mongol royal males were executed even if they were born to Manchu Qing princesses, and all Chahar Mongol royal females were sold into slavery except the Manchu Qing princesses. The Chahar Mongols were then put under the direct control of the Qing Emperor unlike the other Inner Mongol leagues which maintained their autonomy.

Despite officially prohibiting Han Chinese settlement on the Manchu and Mongol lands, by the 18th century the Qing decided to settle Han refugees from northern China who were suffering from famine, floods, and drought into Manchuria and Inner Mongolia so that Han Chinese farmed 500,000 hectares in Manchuria and tens of thousands of hectares in Inner Mongolia by the 1780s.

Ordinary Mongols were not allowed to travel outside their own leagues. Mongols were forbidden by the Qing from crossing the borders of their banners, even into other Mongol Banners and from crossing into neidi (the Han Chinese 18 provinces) and were given serious punishments if they did in order to keep the Mongols divided against each other to benefit the Qing.

During the eighteenth century, growing numbers of Han Chinese settlers had illegally begun to move into the Inner Mongolian steppe. By 1791 there had been so many Han Chinese settlers in the Front Gorlos Banner that the jasak had petitioned the Qing government to legalize the status of the peasants who had already settled there.

During the nineteenth century, the Manchus were becoming increasingly sinicized, and faced with the Russian threat, they began to encourage Han Chinese farmers to settle in both Mongolia and Manchuria. This policy was followed by subsequent governments. The railroads that were being built in these regions were especially useful to the Han Chinese settlers. Land was either sold by Mongol Princes, or leased to Han Chinese farmers, or simply taken away from the nomads and given to Han Chinese farmers. The Jindandao Incident, a rebellion by an ethnic Chinese secret society called Jindandao occurred in Inner Mongolia in November 1891 and massacred 150,000 Mongols before being suppressed by government troops in late December.

Outer Mongolia gained independence from the Qing dynasty in 1911, when the Jebtsundamba Khutugtu of the Khalkha was declared the Bogd Khan of Mongolia. Although almost all banners of Inner Mongolia recognized the Bogd Khan as the supreme ruler of Mongols, the internal strife within the region prevented a full reunification. The Mongol rebellions in Inner Mongolia were counterbalanced by princes who hoped to see a restored Qing dynasty in Manchuria and Mongolia, as they considered the theocratic rule of the Bogd Khan would be against their modernizing objectives for Mongolia. Eventually, the newly formed Republic of China promised a new nation of five races (Han, Manchu, Mongol, Tibetan and Uyghur), and suppressed the Mongol rebellions in the area, forcing the Inner Mongolian princes to recognize the Republic of China.

The Republic of China reorganized Inner Mongolia into provinces:
Some Republic of China maps still show this structure.

The history of Inner Mongolia during the Second World War is complicated, with Japanese invasion and different kinds of resistance movements. In 1931, Manchuria came under the control of the Japanese puppet state Manchukuo, taking some Mongol areas in the Manchurian provinces (i.e. Hulunbuir and Jirim leagues) along. Rehe was also incorporated into Manchukuo in 1933, taking Juu Uda and Josutu leagues along with it. These areas were occupied by Manchukuo until the end of World War II in 1945.

In 1937, the Empire of Japan openly and fully invaded Republic of China by war. On December 8, 1937, Mongolian Prince Demchugdongrub (also known as "De Wang") declared an independence of the remaining parts of Inner Mongolia (i.e. the Suiyuan and Chahar provinces) as Mengjiang, and signed an agreements with Manchukuo and Japan. Its capital was established at Zhangbei (now in Hebei province), with the Japanese puppet government's control extending as far west as the Hohhot region. The Japanese advanced was defeated by Hui Muslim General Ma Hongbin at the Battle of West Suiyuan and Battle of Wuyuan. After 1945, Inner Mongolia has remained part of China.

The Mongol Ulanhu fought against the Japanese.

Ethnic Mongolian guerilla units were created by the Kuomintang Nationalists to fight against the Japanese during the war in the late 30s and early 40s. These Mongol militias were created by the Ejine and Alashaa based commissioner's offices created by the Kuomintang. Prince Demchugdongrob's Mongols were targeted by Kuomintang Mongols to defect to the Republic of China. The Nationalists recruited 1,700 ethnic minority fighters in Inner Mongolia and created war zones in the Tumet Banner, Ulanchab League, and Ordos Yekejuu League.

The Communist movement gradually gained momentum as part of the Third Communist International in Inner Mongolia during the Japanese period. By the end of WWII, the Inner Mongolian faction of the ComIntern had a functional militia, and actively opposed the attempts at independence by De Wang's Chinggisid princes on the grounds of fighting feudalism. Following the end of World War II, the Chinese Communists gained control of Manchuria as well as the Inner Mongolian Communists with decisive Soviet support, and established the Inner Mongolia Autonomous Region in 1947. The Comintern army was absorbed into the People's Liberation Army. Initially the autonomous region included just the Hulunbuir region. Over the next decade, as the communists established the People's Republic of China and consolidated control over mainland China, Inner Mongolia was expanded westwards to include five of the six original leagues (except Josutu League, which remains in Liaoning province), the northern part of the Chahar region, by then a league as well (southern Chahar remains in Hebei province), the Hetao region, and the Alashan and Ejine banners. Eventually, near all areas with sizeable Mongol populations were incorporated into the region, giving present-day Inner Mongolia its elongated shape. The leader of Inner Mongolia during that time, as both regional CPC secretary and head of regional government, was Ulanhu.

During the Cultural Revolution, the administration of Ulanhu was purged, and a wave of repressions was initiated against the Mongol population of the autonomous region. In 1969 much of Inner Mongolia was distributed among surrounding provinces, with Hulunbuir divided between Heilongjiang and Jilin, Jirim going to Jilin, Juu Uda to Liaoning, and the Alashan and Ejine region divided among Gansu and Ningxia. This was reversed in 1979.

Inner Mongolia has seen considerable development since Deng Xiaoping instituted Chinese economic reform in 1978. For about ten years since 2000, Inner Mongolia's GDP growth has been the highest in the country, (along with Guangdong) largely owing to the success of natural resource industries in the region. GDP growth has continually been over 10%, even 15% and connections with the Wolf Economy to the north has helped development. However, growth has come at a cost with huge amounts of pollution and degradation to the grasslands. Attempts to attract ethnic Chinese to migrate from other regions, as well as urbanise those rural nomads and peasants has led to huge amounts of corruption and waste in public spending, such as Ordos City. Acute uneven wealth distribution has further exacerbated ethnic tensions, many indigenous Mongolians feeling they are increasingly marginalised in their own homeland, leading to riots in 2011 and 2013.

Officially Inner Mongolia is classified as one of the provincial-level divisions of North China, but its great stretch means that parts of it belong to Northeast China and Northwest China as well. It borders eight provincial-level divisions in all three of the aforementioned regions (Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, Ningxia, and Gansu), tying with Shaanxi for the greatest number of bordering provincial-level divisions. Most of its international border is with Mongolia, which, in Chinese, is sometimes called "Outer Mongolia", while a small portion is with Russia's Zabaykalsky Krai.
Inner Mongolia largely consists of the northern side of the North China Craton, a tilted and sedimented Precambrian block. In the extreme southwest is the edge of the Tibetan Plateau where the autonomous region’s highest peak, Main Peak in the Helan Mountains reaches, and is still being pushed up today in short bursts. Most of Inner Mongolia is a plateau averaging around in altitude and covered by extensive loess and sand deposits. The northern part consists of the Mesozoic era Khingan Mountains, and is owing to the cooler climate more forested, chiefly with Manchurian elm, ash, birch, Mongolian oak and a number of pine and spruce species. Where discontinuous permafrost is present north of Hailar District, forests are almost exclusively coniferous. In the south the natural vegetation is grassland in the east and very sparse in the arid west, and grazing is the dominant economic activity.

Owing to the ancient, weathered rocks lying under its deep sedimentary cover, Inner Mongolia is a major mining district, possessing large reserves of coal, iron ore and rare-earth minerals, which have made it a major industrial region today.

Due to its elongated shape, Inner Mongolia has a wide variety of regional climates. Throughout the region, the climate is based off a four-season, monsoon climate. The winters in Inner Mongolia are very long, cold, and dry with frequent blizzards, though snowfall is so light that Inner Mongolia has no modern glaciers even on the highest Helan peaks. The spring is short, mild and arid, with large, dangerous sandstorms, whilst the summer is very warm to hot and relatively humid except in the west where it remains dry. Autumn is brief and sees a steady cooling, with temperatures below reached in October in the north and November in the south.

Officially, most of Inner Mongolia is classified as either a cold arid or steppe regime (Köppen "BWk, BSk", respectively). The small portion besides these are classified as humid continental (Köppen "Dwb") in the northeast, or subarctic (Köppen "Dwc") in the far north near Hulunbuir.

Inner Mongolia is divided into twelve prefecture-level divisions. Until the late 1990s, most of Inner Mongolia's prefectural regions were known as "Leagues" (), a usage retained from Mongol divisions of the Qing dynasty. Similarly, county-level divisions are often known as "Banners" (). Since the 1990s, numerous Leagues have converted into prefecture-level cities, although Banners remain. The restructuring led to the conversion of primate cities in most leagues to convert to districts administratively (i.e.: Hailar, Jining and Dongsheng). Some newly founded prefecture-level cities have chosen to retain the original name of League (i.e.: Hulunbuir, Bayannur and Ulanqab), some have adopted the Chinese name of their primate city (Chifeng, Tongliao), and one League (Yekejuu) simply renamed itself Ordos. Despite these recent administrative changes, there is no indication that the Alxa, Hinggan, and Xilingol Leagues will convert to prefecture-level cities in the near future.

The twelve prefecture-level divisions of Inner Mongolia are subdivided into 102 county-level divisions, including 22 districts, 11 county-level cities, 17 counties, 49 banners, and 3 autonomous banners. Those are in turn divided into 1425 township-level divisions, including 532 towns, 407 townships, 277 sumu, eighteen ethnic townships, one ethnic sumu, and 190 subdistricts. At the end of 2017, the total population of Inner-Mongolia is 25.29 million.

Farming of crops such as wheat takes precedence along the river valleys. In the more arid grasslands, herding of goats, sheep and so on is a traditional method of subsistence. Forestry and hunting are somewhat important in the Greater Khingan ranges in the east. Reindeer herding is carried out by Evenks in the Evenk Autonomous Banner. More recently, growing grapes and winemaking have become an economic factor in the Wuhai area.

Inner Mongolia has an abundance of resources especially coal, cashmere, natural gas, rare-earth elements, and has more deposits of naturally occurring niobium, zirconium and beryllium than any other province-level region in China. However, in the past, the exploitation and utilisation of resources were rather inefficient, which resulted in poor returns from rich resources. Inner Mongolia is also an important coal production base, with more than a quarter of the world's coal reserves located in the province. It plans to double annual coal output by 2010 (from the 2005 volume of 260 million tons) to 500 million tons of coal a year.

Industry in Inner Mongolia has grown up mainly around coal, power generation, forestry-related industries, and related industries.
Inner Mongolia now encourages six competitive industries: energy, chemicals, metallurgy, equipment manufacturing, processing of farm (including dairy) produce, and high technology. Well-known Inner Mongolian enterprises include companies such as ERDOS, Yili, and Mengniu.

The nominal GDP of Inner Mongolia in 2015 was 1.8 trillion yuan (US$272.1 billion), with an average annual increase of 10% from the period 2010-2015. Its per capita GDP reached US$11,500 in 2015, ranking No.4th among all the 31 provinces of China, only after Shanghai, Beijing and Tianjin.

As with much of China, economic growth has led to a boom in construction, including new commercial development and large apartment complexes.

In addition to its large reserves of natural resources, Inner Mongolia also has the largest usable wind power capacity in China thanks to strong winds which develop in the province's grasslands. Some private companies have set up wind parks in parts of Inner Mongolia such as Bailingmiao, Hutengliang and Zhouzi.

Hohhot Export Processing Zone was established on June 21, 2002, by the State Council, which is located in the west of the Hohhot, with a planning area of. Industries encouraged in the export processing zone include Electronics Assembly & Manufacturing, Telecommunications Equipment, Garment and Textiles Production, Trading and Distribution, Biotechnology/Pharmaceuticals, Food/Beverage Processing, Instruments & Industrial Equipment Production, Medical Equipment and Supplies, Shipping/Warehousing/Logistics, Heavy Industry.

Under the Constitution of the People's Republic of China, articles 112-122, autonomous regions have limited autonomy in both the political and economic arena. Autonomous regions have more discretion in administering economic policy in the region in accordance with national guidelines. Structurally, the Chairman—who legally must be an ethnic minority and is usually ethnic Mongolian—is always kept in check by the Communist Party Regional Committee Secretary, who is usually from a different part of China (to reduce corruption) and Han Chinese. The current party secretary is Wang Jun. The Inner Mongolian government and its subsidiaries follow roughly the same structure as that of a Chinese province. With regards to economic policy, as a part of increased federalism characteristics in China, Inner Mongolia has become more independent in implementing its own economic roadmap.

The position of Chairman of Inner Mongolia alternates between Khorchin Mongols in the east and the Tumed Mongols in the west. Since the end of the Cultural Revolution, this convention has not been broken. The family of Ulanhu has retained influence in regional politics ever since the founding the People's Republic. His son Buhe and granddaughter Bu Xiaolin both served as Chairman of the region.

When the autonomous region was established in 1947, Han Chinese comprised 83.6% of the population, while the Mongols comprised 14.8% of the population. By 2010, the percentage of Han Chinese had dropped to 79.5%. While the Hetao region along the Yellow River has always alternated between farmers from the south and nomads from the north, the most recent wave of Han Chinese migration began in the early 18th century with encouragement from the Qing dynasty, and continued into the 20th century. Han Chinese live mostly in the Hetao region as well as various population centres in central and eastern Inner Mongolia. Over 70% of Mongols are concentrated in less than 18% of Inner Mongolia's territory (Hinggan League, and the prefectures of Tongliao and Chifeng).

Mongols are the second largest ethnic group, comprising 17.11% of the population as of the 2010 census. They include many diverse Mongolian-speaking groups; groups such as the Buryats and the Oirats are also officially considered to be Mongols in China. In addition to the Manchus, three other Tungusic ethnic groups, the Daur, the Oroqen, and the Evenks also populate parts of northeastern Inner Mongolia.

Many of the traditionally nomadic Mongols have settled in permanent homes as their pastoral economy was collectivized during the Mao Era, and some have taken jobs in cities as migrant labourers; however, some Mongols continue in their nomadic tradition. In practice, highly educated Mongols tend to migrate to big urban centers after which they become essentially indistinct with ethnic Han Chinese populations.

Inter-marriage between Mongol and non-Mongol populations is very common, particularly in areas where Mongols are in regular contact with other groups. There was little cultural stigma within Mongol families for marrying outside the ethnic group, and in urban centers in particular, Mongol men and women married non-Mongols at relatively similar rates. The rates of intermarriage stands in very sharp contrast to ethnic Tibetans and Uyghurs in their respective autonomous regions. By the 1980s, for instance, in the former Jirim League, nearly 40% of marriages with at least one Mongol spouse was a mixed Mongol-Han Chinese marriage. However, anecdotal reports have also demonstrated an increase in Mongol-female, Han Chinese-male pairings in which the woman is of a rural background, ostensibly shutting rural Mongol males from the marriage market as the sex ratio in China becomes more skewed with a much higher proportion of men.

There is also a significant number of Hui and Koreans.

"Population numbers exclude members of the People's Liberation Army in active service based in Inner Mongolia."

Alongside Chinese, Mongolian is the official provincial language of the Inner Mongolia Autonomous Region, where there are at least 4.1 million ethnic Mongols. Across the whole of China, the language is spoken by roughly half of the country's 5.8 million ethnic Mongols (2005 estimate) However, the exact number of Mongolian speakers in China is unknown, as there is no data available on the language proficiency of that country's citizens. The use of Mongolian in China, specifically in Inner Mongolia, has witnessed periods of decline and revival over the last few hundred years. The language experienced a decline during the late Qing period, a revival between 1947 and 1965, a second decline between 1966 and 1976, a second revival between 1977 and 1992, and a third decline between 1995 and 2012. However, in spite of the decline of the Mongolian language in some of Inner Mongolia's urban areas and educational spheres, the ethnic identity of the urbanized Chinese-speaking Mongols is most likely going to survive due to the presence of urban ethnic communities. The multilingual situation in Inner Mongolia does not appear to obstruct efforts by ethnic Mongols to preserve their language. Although an unknown number of Mongols in China, such as the Tumets, may have completely or partially lost the ability to speak their language, they are still registered as ethnic Mongols and continue to identify themselves as ethnic Mongols. The children of inter-ethnic Mongol-Chinese marriages also claim to be and are registered as ethnic Mongols.

By law, all street signs, commercial outlets, and government documents must be bilingual, written in both Mongolian and Chinese. There are three Mongolian TV channels in the Inner Mongolia Satellite TV network. In public transportation, all announcements are to be bilingual.

The Han Chinese of Inner Mongolia speak a variety of dialects, depending on the region. Those in the eastern parts tend to speak Northeastern Mandarin, which belongs to the Mandarin group of dialects; those in the central parts, such as the Yellow River valley, speak varieties of Jin, another subdivision of Chinese, due to its proximity to other Jin-speaking areas in China such as the Shanxi province. Cities such as Hohhot and Baotou both have their unique brand of Jin Chinese such as the Zhangjiakou–Hohhot dialect which are sometimes incomprehensible with dialects spoken in northeastern regions such as Hailar.

The vast grasslands have long symbolised Inner Mongolia. Mongolian art often depicts the grassland in an uplifting fashion and emphasizes Mongolian nomadic traditions. The Mongols of Inner Mongolia still practice their traditional arts. Inner Mongolian cuisine has Mongol roots and consists of dairy-related products and "hand-held lamb" (). In recent years, franchises based on Hot pot have appeared in Inner Mongolia, the best known of which is "Xiaofeiyang". Notable Inner Mongolian commercial brand names include Mengniu and Yili, both of which began as dairy product and ice cream producers.

Among the Han Chinese of Inner Mongolia, Jinju () or Shanxi Opera is a popular traditional form of entertainment. See also: Shanxi. A popular career in Inner Mongolia is circus acrobatics. The internationally known Inner Mongolia Acrobatic Troupe travels and performs with the renowned Ringling Bros. and Barnum and Bailey Circus.

According to a survey held in 2004 by the Minzu University of China, about 80% of the population of the region practice the worship of Heaven (that is named "Tian" in the Chinese tradition and "Tenger" in the Mongolian tradition) and of "ovoo/aobao".

Official statistics report that 12.1% of the population (3 million people) are members of Tibetan Buddhist groups. According to the Chinese Spiritual Life Survey of 2007 and the Chinese General Social Survey of 2009, Christianity is the religious identity of 2% of the population of the region; and Chinese ancestral religion the professed belonging of 2.36%, while a demographic analysis of the year 2010 reported that Muslims comprise the 0.91%.

The cult of Genghis Khan, present in the form of various Genghis Khan temples, is a tradition of Mongolian shamanism, in which he is considered a cultural hero and divine ancestor, an embodiment of the "Tenger" (Heaven, God of Heaven). His worship in special temples, greatly developed in Inner Mongolia since the 1980s, is also shared by the Han Chinese, claiming his spirit as the founding principle of the Yuan dynasty.

Tibetan Buddhism (Mongolian Buddhism, locally also known as "Yellow Buddhism") is the dominant form of Buddhism in Inner Mongolia, also practiced by many Han Chinese. Another form of Buddhism, practiced by the Chinese, are the schools of Chinese Buddhism.

In the capital city Hohhot:

Elsewhere in Inner Mongolia:

One of China's space vehicle launch facilities, Jiuquan Satellite Launch Center, is located in the extreme west of Inner Mongolia, in the Alxa League's Ejin Banner. It was founded in 1958, making it the PRC's first launch facility. More Chinese launches have occurred at Jiuquan than anywhere else. As with all Chinese launch facilities, it is remote and generally closed to the public. It is named as such since Jiuquan is the nearest urban center, although Jiuquan is in the nearby province of Gansu. Many space vehicles have also made their touchdowns in Inner Mongolia. For example, the crew of Shenzhou 6 landed in Siziwang Banner, near Hohhot.All of the above are under the authority of the autonomous region government. Institutions without full-time bachelor programs are not listed.

The status of certain varieties in the Mongolic group—whether they are languages distinct from Mongolian or just dialects of it—is disputed. There are at least three such varieties: Oirat (including the Kalmyk variety) and Buryat, both of which are spoken in Russia, Mongolia, and China; and Ordos, spoken around Inner Mongolia's Ordos City.

Mongolian language

The Mongolian language (in Mongolian script: '; in Mongolian Cyrillic:, ') is the official language of Mongolia and both the most widely-spoken and best-known member of the Mongolic language family. The number of speakers across all its dialects may be 5.2 million, including the vast majority of the residents of Mongolia and many of the Mongolian residents of the Inner Mongolia Autonomous Region.
In Mongolia, the Khalkha dialect, written in Cyrillic (and at times in Latin for social networking), is predominant, while in Inner Mongolia, the language is dialectally more diverse and is written in the traditional Mongolian script. In the discussion of grammar to follow, the variety of Mongolian treated is Standard Khalkha Mongolian (i.e., the standard written language as formalized in the writing conventions and in the school grammar), but much of what is to be said is also valid for vernacular (spoken) Khalkha and for other Mongolian dialects, especially Chakhar.

Some classify several other Mongolic languages like Buryat and Oirat as dialects of Mongolian, but this classification is not in line with the current international standard.

Mongolian has vowel harmony and a complex syllabic structure for a Mongolic language that allows clusters of up to three consonants syllable-finally. It is a typical agglutinative language that relies on suffix chains in the verbal and nominal domains. While there is a basic word order, subject–object–predicate, ordering among noun phrases is relatively free, so grammatical roles are indicated by a system of about eight grammatical cases. There are five voices. Verbs are marked for voice, aspect, tense, and epistemic modality/evidentiality. In sentence linking, a special role is played by converbs.

Modern Mongolian evolved from Middle Mongol, the language spoken in the Mongol Empire of the 13th and 14th centuries. In the transition, a major shift in the vowel-harmony paradigm occurred, long vowels developed, the case system changed slightly, and the verbal system was restructured. Mongolian is related to the extinct Khitan language. It was believed that Mongolian is related to Turkic,
Tungusic, Korean and Japonic languages but this view is now seen as obsolete. These languages have been grouped under the now discredited Altaic language family and contrasted with the Mainland Southeast Asia linguistic area. Mongolian literature is well attested in written form from the 13th century but has earlier Mongolic precursors in the literature of the Khitan and other Xianbei peoples. The Inscription of Hüis Tolgoi dated to 630 CE is currently the oldest substantial Mongolic or Para-Mongolic text discovered.

Mongolian is the official national language of Mongolia, where it is spoken (but not written) by nearly 3.6 million people (2014 estimate), and the official provincial language (both spoken and written forms) of Inner Mongolia, China, where there are at least 4.1 million ethnic Mongols. Across the whole of China, the language is spoken by roughly half of the country's 5.8 million ethnic Mongols (2005 estimate) However, the exact number of Mongolian speakers in China is unknown, as there is no data available on the language proficiency of that country's citizens. The use of Mongolian in Inner Mongolia, has witnessed periods of decline and revival over the last few hundred years. The language experienced a decline during the late Qing period, a revival between 1947 and 1965, a second decline between 1966 and 1976, a second revival between 1977 and 1992, and a third decline between 1995 and 2012. However, in spite of the decline of the Mongolian language in some of Inner Mongolia's urban areas and educational spheres, the ethnic identity of the urbanized Chinese-speaking Mongols is most likely going to survive due to the presence of urban ethnic communities. The multilingual situation in Inner Mongolia does not appear to obstruct efforts by ethnic Mongols to preserve their language. Although an unknown number of Mongols in China, such as the Tumets, may have completely or partially lost the ability to speak their language, they are still registered as ethnic Mongols and continue to identify themselves as ethnic Mongols. The children of inter-ethnic Mongol-Chinese marriages also claim to be and are registered as ethnic Mongols.

Mongolian belongs to the Mongolic languages. The delimitation of the Mongolian language within Mongolic is a much disputed theoretical problem, one whose resolution is impeded by the fact that existing data for the major varieties is not easily arrangeable according to a common set of linguistic criteria. Such data might account for the historical development of the Mongolian dialect continuum, as well as for its sociolinguistic qualities. Though phonological and lexical studies are comparatively well developed, the basis has yet to be laid for a comparative morphosyntactic study, for example between such highly diverse varieties as Khalkha and Khorchin.

There is no disagreement that the Khalkha dialect of the Mongolian state is Mongolian. Beyond this one point, however, agreement ends. For example, the influential classification of Sanžeev (1953) proposed a "Mongolian language" consisting of just the three dialects Khalkha, Chakhar, and Ordos, with Buryat and Oirat judged to be independent languages. On the other hand, Luvsanvandan (1959) proposed a much broader "Mongolian language" consisting of a Central dialect (Khalkha, Chakhar, Ordos), an Eastern dialect (Kharchin, Khorchin), a Western dialect (Oirat, Kalmyk), and a Northern dialect (consisting of two Buryat varieties). Some Western scholars propose that the relatively well researched Ordos variety is an independent language due to its conservative syllable structure and phoneme inventory. While the placement of a variety like Alasha, which is under the cultural influence of Inner Mongolia but historically tied to Oirat, and of other border varieties like Darkhad would very likely remain problematic in any classification, the central problem remains the question of how to classify Chakhar, Khalkha, and Khorchin in relation to each other and in relation to Buryat and Oirat. The split of into before *i and before all other reconstructed vowels, which is found in Mongolia but not in Inner Mongolia, is often cited as a fundamental distinction, for example Proto-Mongolic ', Khalkha, Chakhar 'year' versus Proto-Mongolic ', Khalkha, Chakhar 'few'. On the other hand, the split between the past tense verbal suffixes -' in the Central varieties vs. -' in the Eastern varieties is usually seen as a merely stochastic difference.

In Inner Mongolia, official language policy divides the Mongolian language into three dialects: Southern Mongolian, Oirat, and Barghu-Buryat. Southern Mongolian is said to consist of Chakhar, Ordos, Baarin, Khorchin, Kharchin, and Alasha. The authorities have synthesized a literary standard for Mongolian in whose grammar is said to be based on Southern Mongolian and whose pronunciation is based on the Chakhar dialect as spoken in the Plain Blue Banner. Dialectologically, however, western Southern Mongolian dialects are closer to Khalkha than they are to eastern Southern Mongolian dialects: for example, Chakhar is closer to Khalkha than to Khorchin.

Besides Mongolian, or "Central Mongolic", other languages in the Mongolic grouping include Dagur, spoken in eastern Inner Mongolia, Heilongjiang, and in the vicinity of Tacheng in Xinjiang; the Shirongolic subgroup Shira Yugur, Bonan, Dongxiang, Monguor, and Kangjia, spoken in Qinghai and Gansu regions; and the possibly extinct Moghol of Afghanistan.

As for the classification of the Mongolic family relative to other languages, the Altaic theory (which is increasingly less well received among linguists) proposes that the Mongolic family is a member of a larger, now discredited Altaic family that would also include the Turkic and Tungusic, and usually Koreanic languages and Japonic languages as well.

The following description is based primarily on the Khalkha dialect as spoken in Ulaanbaatar, Mongolia's capital. The phonologies of other varieties such as Ordos, Khorchin, and even Chakhar, differ considerably.
This section discusses the phonology of Khalkha Mongolian with subsections on Vowels, Consonants, Phonotactics and Stress.

The standard language has seven monophthong vowel phonemes. They are aligned into three vowel harmony groups by a parameter called ATR (advanced tongue root); the groups are −ATR, +ATR, and neutral. This alignment seems to have superseded an alignment according to oral backness. However, some scholars still describe Mongolian as being characterized by a distinction between front vowels and back vowels, and the front vowel spellings 'ö' and 'ü' are still often used in the West to indicate two vowels which were historically front. The Mongolian vowel system also has rounding harmony.

Length is phonemic for vowels, and each of the seven phonemes occurs short or long. Phonetically, short has become centralized to the central vowel.

In the following table, the seven vowel phonemes, with their length variants, are arranged and described phonetically.

Khalkha also has four diphthongs:.

ATR harmony. Mongolian divides vowels into three groups in a system of vowel harmony:

As mentioned, for historical reasons these have traditionally been labeled as "front" vowels and "back" vowels. Indeed, in Romanized transcription of Mongolian, the vowels and are often conventionally rendered as and, while the vowels and are expressed as and (this is also the case in the nonphonological sections of this article). However, for modern Mongolian phonology, it seems more appropriate to instead characterize the two vowel-harmony groups by the dimension of tongue root position. There is also one neutral vowel,, not belonging to either group.

All the vowels in a noncompound word, including all its suffixes, must belong to the same group. If the first vowel is −ATR, then every vowel of the word must be either or a −ATR vowel. Likewise, if the first vowel is a +ATR vowel, then every vowel of the word must be either or a +ATR vowel. In the case of suffixes, which must change their vowels to conform to different words, two patterns predominate. Some suffixes contain an archiphoneme that can be realized as. For example:Other suffixes can occur in being realized as, in which case all −ATR vowels lead to and all +ATR vowels lead to. For example:If the only vowel in the word stem is, the suffixes will use the +ATR suffix forms.

Rounding harmony. Mongolian also has rounding harmony, which does not apply to close vowels. If a stem contains (or ), a suffix that is specified for an open vowel will have (or, respectively) as well. However, this process is blocked by the presence of (or ) and. E.g. "came in", but "inserted".

Vowel length. The pronunciation of long and short vowels depends on the syllable's position in the word. In word-initial syllables there is a phonemic contrast in length. A long vowel has about 208% the length of a short vowel. In word-medial and word-final syllables, formerly long vowels are now only 127% as long as short vowels in initial syllables, but they are still distinct from initial-syllable short vowels. Short vowels in noninitial syllables differ from short vowels in initial syllables by being only 71% as long and by being centralized in articulation. As they are nonphonemic, their position is determined according to phonotactic requirements.

The following table lists the consonants of Khalkha Mongolian. The consonants enclosed in parentheses occur only in loanwords.

Mongolian lacks the voiced lateral approximant, ; instead, it has a voiced alveolar lateral fricative,, which is often realized as voiceless. In word-final position, (if not followed by a vowel in historical forms) is realized as. The occurrence of palatalized consonant phonemes seems to be restricted to words that contain [−ATR] vowels. Aspirated consonants are preaspirated in medial and word-final contexts, devoicing preceding consonants and vowels. Devoiced short vowels are often deleted.

The maximal syllable is CVVCCC, where the last C is a word-final suffix. A single short vowel rarely appears in syllable-final position. If a word was monosyllabic historically, *CV has become CVV. is restricted to codas (else it becomes ), and and do not occur in codas for historical reasons. For two-consonant clusters, the following restrictions obtain:Clusters that do not conform to these restrictions will be broken up by an epenthetic nonphonemic vowel in a syllabification that takes place from right to left. For example, "hojor" 'two', "ažil" 'work', and "saarmag" 'neutral' are, phonemically,,, and respectively. In such cases, an epenthetic vowel is inserted so as to prevent disallowed consonant clusters. Thus, in the examples given above, the words are phonetically,, and. The phonetic form of the epenthetic vowel follows from vowel harmony triggered by the vowel in the preceding syllable. Usually it is a centralized version of the same sound, with the following exceptions: preceding produces ; will be ignored if there is a nonneutral vowel earlier in the word; and a postalveolar or palatalized consonant will be followed by an epenthetic, as in.

Stress in Mongolian is nonphonemic (does not distinguish different meanings) and thus is considered to depend entirely on syllable structure. But scholarly opinions on stress placement diverge sharply. Most native linguists, regardless of which dialect they speak, claim that stress falls on the first syllable. Between 1941 and 1975, several Western scholars proposed that the leftmost heavy syllable gets the stress. Yet other positions were taken in works published between 1835 and 1915.

Walker (1997) proposes that stress falls on the rightmost heavy syllable unless this syllable is word-final:

A "heavy syllable" is here defined as one that is at least the length of a full vowel; short word-initial syllables are thereby excluded. If a word is bisyllabic and the only heavy syllable is word-final, it gets stressed anyway. In cases where there is only one phonemic short word-initial syllable, even this syllable can get the stress:

More recently, the most extensive collection of phonetic data so far in Mongolian studies has been applied to a partial account of stress placement in the closely related Chakhar dialect. The conclusion is drawn that di- and trisyllabic words with a short first syllable are stressed on the second syllable. But if their first syllable is long, then the data for different acoustic parameters seems to support conflicting conclusions: intensity data often seems to indicate that the first syllable is stressed, while F0 seems to indicate that it is the second syllable that is stressed.

The grammar here is also based primarily on Khalkha Mongolian. Unlike the phonology, most of what is said about morphology and syntax also holds true for Chakhar, while Khorchin is somewhat more diverse.

Modern Mongolian is an agglutinative, almost exclusively suffixing language, the only exception being reduplication. Most of the suffixes consist of a single morpheme. There are many derivational morphemes. For example, the word "bajguullagynh" consists of the root "baj"- 'to be', an epenthetic -"g"-, the causative -"uul"- (hence 'to found'), the derivative suffix -"laga" that forms nouns created by the action (like -"ation" in 'organisation') and the complex suffix –"ynh" denoting something that belongs to the modified word (-"yn" would be genitive).

Nominal compounds are quite frequent. Some derivational verbal suffixes are rather productive, e.g. "jar'"- 'to speak', "jarilts"- 'to speak with each other'. Formally, the independent words derived using verbal suffixes can roughly be divided into three classes: final verbs, which can only be used sentence-finally, i.e. -"na" (mainly future or generic statements) or –"ø" (second person imperative); participles (often called "verbal nouns"), which can be used clause-finally or attributively, i.e. -"san" (perfect-past) or -"maar" ('want to'); and converbs, which can link clauses or function adverbially, i.e. -"ž" (qualifies for any adverbial function or neutrally connects two sentences) or -"tal" (the action of the main clause takes place until the action expressed by the suffixed verb begins).

Roughly speaking, Mongolian has eight cases: nominative (unmarked), genitive, dative, accusative, ablative, instrumental, comitative and directional. If a direct object is definite, it must take the accusative, while it must take the nominative if it is unspecific. In addition to case, a number of postpositions exist that usually govern genitive, ablative, or comitative case or a form of the nominative that has sometimes -Vn either for lexical historical reasons or analogy (thus maybe becoming an attributive case suffix). Nouns can take reflexive-possessive clitics indicating that the marked noun is possessed by the subject of the sentence: "bi najz(-)aa avarsan" I friend- save- 'I saved my friend'. However, there are also somewhat noun-like adjectives to which case suffixes seemingly cannot be attached directly unless there is ellipsis. Plurality may be left unmarked, but there are overt plurality markers, some of which are restricted to humans. A noun that is modified by a numeral usually does not take any plural affix.

Personal pronouns exist for the first and second person, while the old demonstrative pronouns have come to form third person (proximal and distal) pronouns. Other word (sub-)classes include interrogative pronouns, conjunctions (which take participles), spatials, and particles, the last being rather numerous.

Negation is mostly expressed by "-güj" after participles and by the negation particle "biš" after nouns and adjectives; negation particles preceding the verb (for example in converbal constructions) exist, but tend to be replaced by analytical constructions.

The noun phrase has the order: demonstrative pronoun/numeral, adjective, noun. Attributive sentences precede the whole NP. Titles or occupations of people, low numerals indicating groups, and focus clitics are put behind the head noun. Possessive pronouns (in different forms) may either precede or follow the NP. Examples:

The verbal phrase consists of the predicate in the center, preceded by its complements and by the adverbials modifying it and followed (mainly if the predicate is sentence-final) by modal particles, as in the following example with predicate "bičsen":

In this clause the adverbial, "helehgüjgeer" 'without saying [so]' must precede the predicate's complement, "üünijg" 'it-' in order to avoid syntactic ambiguity, since "helehgüjgeer" is itself derived from a verb and hence an "üünijg" preceding it could be construed as its complement. If the adverbial was an adjective such as "hurdan" 'fast', it could optionally immediately precede the predicate. There are also cases in which the adverb must immediately precede the predicate.

For Khalkha, the most complete treatment of the verbal forms is Luvsanvandan (ed.) 1987. However, the analysis of predication presented here, while valid for Khalkha, is adapted from the description of Khorchin by Matsuoka 2007.

Most often, of course, the predicate consists of a verb. However, there are several types of nominal predicative constructions, with or without a copula. Auxiliaries that express direction and aktionsart (among other meanings) can with the assistance of a linking converb occupy the immediate postverbal position, e.g. "uuž orhison" drink- leave- 'drank up'. The next position is filled by converb suffixes in connection with the auxiliary, "baj-" 'to be', e.g. "ter güjž bajna" s/he run- be-'she is running'. Suffixes occupying this position express grammatical aspect, e.g., progressive and resultative. In the next position, participles followed by "baj-" may follow, e.g., "ter irsen bajna" s/he come- be- 'he has come'. Here, an explicit perfect and habituality can be marked, which is aspectual in meaning as well. This position may be occupied by multiple suffixes in a single predication, and it can still be followed by a converbal Progressive. The last position is occupied by suffixes that express tense, evidentiality, modality, and aspect.

Unmarked phrase order is subject–object–predicate. While the predicate generally has to remain in clause-final position, the other phrases are free to change order or to wholly disappear. The topic tends to be placed clause-initially, new information rather at the end of the clause. Topic can be overtly marked with "bol", which can also mark contrastive focus, overt additive focus ('even, also') can be marked with the clitic "č", and overt restrictive focus with the clitic "l" ('only').

The inventory of voices in Mongolian consists of passive, causative, reciprocal, plurative, and cooperative. In a passive sentence, the verb takes the suffix -"gd"- and the agent takes either dative or instrumental case, the first of which is more common. In the causative, the verb takes the suffix -"uul"-, the causee (the person caused to do something) in a transitive action (e.g., 'raise') takes dative or instrumental case, and the causee in an intransitive action (e.g., 'rise') takes accusative case. Causative morphology is also used in some passive contexts:

The semantic attribute of animacy is syntactically important: thus the sentence, 'the bread was eaten by me', which is acceptable in English, would not be acceptable in Mongolian. The reciprocal voice is marked by -"ld"-, the plurative by -"tsgaa"-, and the cooperative by -"lts"-.

Mongolian allows for adjectival depictives that relate to either the subject or the direct object, e.g. "Ljena nücgen untdag" 'Lena sleeps naked', while adjectival resultatives are marginal.

One way to conjoin clauses is to have the first clause end in a converb, as in the following example using the converb "-bol":

Some verbal nouns in the dative (or less often in the instrumental) function very similar to converbs: e.g., replacing "olbol" in the preceding sentence with "olohod" find- yields 'when we find it we'll give it to you'. Quite often, postpositions govern complete clauses. In contrast, conjunctions take verbal nouns without case:

Finally, there is a class of particles, usually clause-initial, that are distinct from conjunctions but that also relate clauses:

Mongolian has a complementizer auxiliary verb "ge"- very similar to Japanese "to iu". "ge"- literally means 'to say' and in converbal form "gež" precedes either a psych verb or a verb of saying. As a verbal noun like "gedeg" (with "n'" or case) it can form a subset of complement clauses. As "gene" it may function as an evidentialis marker.

Mongolian clauses tend to be combined paratactically, which sometimes gives rise to sentence structures which are subordinative despite resembling coordinative structures in European languages:

In the subordinate clause the subject, if different from the subject of main clause, sometimes has to take accusative or genitive case. There is marginal occurrence of subjects taking ablative case as well. Subjects of attributive clauses in which the head has a function (as is the case for all English relative clauses) usually require that if the subject is not the head, then it take the genitive, e.g. "tüünij idsen hool" that.one- eat- meal 'the meal that s/he had eaten'.

Mongolian first adopted loanwords from Old Turkic, Sanskrit (these often through Uighur), Persian, Arabic, Tibetan, Tungusic, and Chinese. However, more recent loanwords come from Russian, English, and Mandarin Chinese (mainly in Inner Mongolia). Language commissions of the Mongolian state continuously translate new terminology into Mongolian, so as the Mongolian vocabulary now has "jerönhijlögč" 'president' ("generalizer") and "šar ajrag" 'beer' ("yellow kumys"). There are several loan translations, e.g., "galt tereg" 'train' ('fire-having cart') from Chinese huǒchē (火车, fire cart) 'train'. Other loan translations include "mön chanar" (essence) from Chinese shízhì (实质, true quality), "khün am" (population) from Chinese rénkǒu (人口, person mouth), "erdene shish" (corn, maize) from Chinese yùmǐ (玉米, jade rice) and "bügd nairamdakh uls" (republic) from Chinese gònghéguó (共和国, public collaboration nation).In the 20th century there were numerous Russian loanwords concerning daily life: "doktor" (doctor), "shokolad" (chocolate), "vagon" (train wagon), "kalendar" (calendar), sistem, "podvoolk" (from "futbolka", T-shirt), and "mashin" (car). In more recent times, due to socio-political changes, Mongolian has loaned various words from English; some which have gradually evolved as official terms: "menejment", "computer", "fail" (file), "marketing", "kredit", "onlain" (online), "mesej" (message). Most of the latter are confined to the Mongolian state.

Despite having a diverse range of loanwords, Mongolian dialects such as Khalkha and Khorchin, within a comparative vocabulary of 452 words of Common Mongolic vocabulary, retain as many as 95% of these native words, contrasting e.g. with Southern Mongolic languages at 39–77% retentions.

Mongolian has been written in a variety of alphabets, making it a language with one of the largest number of scripts used historically. The earliest stages of Mongolian (Xianbei, Wuhuan languages) may have used an indigenous runic script as indicated by Chinese sources. The Khitan large script adopted in 920 CE is an early Mongol (or according to some, para-Mongolic) script.

The traditional Mongolian script was adapted from Uyghur script probably at the very beginning of the 13th century and from that time underwent some minor disambiguations and supplementations. Between 1930 and 1932, a short-lived attempt was made to introduce the Latin script in the Mongolian state, and after a preparatory phase, the Mongolian Cyrillic script was declared mandatory by government decree. It has been argued that the 1941 introduction of the Cyrillic script, with its smaller discrepancy between written and spoken form, contributed to the success of the large-scale government literacy campaign, which increased the literacy rate from 17.3% to 73.5% between 1941 and 1950. Earlier government campaigns to eradicate illiteracy, employing the traditional script, had only managed to raise literacy from 3.0% to 17.3% between 1921 and 1940. From 1991 to 1994, an attempt at reintroducing the traditional alphabet failed in the face of popular resistance. In informal contexts of electronic text production, the use of the Latin alphabet is common.

In the People's Republic of China, Mongolian is a co-official language with Mandarin Chinese in some regions, notably the entire Inner Mongolia Autonomous Region. The traditional alphabet has always been used there, although Cyrillic was considered briefly before the Sino-Soviet split. There are two types of written Mongolian used in China: the traditional Mongolian script, which is official among Mongols nationwide, and the Clear script, used predominantly among Oirats in Xinjiang.

The earliest surviving Mongolian text may be the, a report on sports composed in Mongolian script on stone, which is most often dated at 1224 or 1225. The Mongolian-Armenian wordlist of 55 words compiled by Kirakos of Gandzak (13th century) is the first written record of Mongolian words. From the 13th to the 15th centuries, Mongolian language texts were written in four scripts (not counting some vocabulary written in Western scripts): Uyghur Mongolian (UM) script (an adaptation of the Uyghur alphabet), 'Phags-pa script (Ph) (used in decrees), Chinese (SM) ("The Secret History of the Mongols"), and Arabic (AM) (used in dictionaries). While they are the earliest texts available, these texts have come to be called "Middle Mongol" in scholarly practice. The documents in UM script show some distinct linguistic characteristics and are therefore often distinguished by terming their language "Preclassical Mongolian".

The Yuan dynasty referred to the Mongolian language in Chinese as "Guoyu" (), which means "National language", a term also used by other non-Han dynasties to refer to their languages such as the Manchu language during the Qing dynasty, the Jurchen language during the Jin dynasty (1115–1234), the Khitan language during the Liao dynasty, and the Xianbei language during the Northern Wei.

The next distinct period is Classical Mongolian, which is dated from the 17th to the 19th century. This is a written language with a high degree of standardization in orthography and syntax that sets it quite apart from the subsequent Modern Mongolian. The most notable documents in this language are the Mongolian Kangyur and Tengyur as well as several chronicles. In 1686, the Soyombo alphabet (Buddhist texts) was created, giving distinctive evidence on early classical Mongolian phonological peculiarities.

The research into the reconstruction of the consonants of Middle Mongol has engendered several controversies. Middle Mongol had two series of plosives, but there is disagreement as to which phonological dimension they lie on, whether aspiration or voicing. The early scripts have distinct letters for velar plosives and uvular plosives, but as these are in complementary distribution according to vowel harmony class, only two back plosive phonemes, *"/k/", *' (~ *"[k]", *') are to be reconstructed. One prominent long running disagreement concerns certain correspondences of word medial consonants among the four major scripts (UM, SM, AM, and Ph, which were discussed in the preceding section). Word medial "/k/" of Uyghur Mongolian (UM) has, not one, but two correspondences with the three other scripts: either /k/ or zero. Traditional scholarship has reconstructed *"/k/" for both correspondences, arguing that *"/k/" got lost in some instances, which raises the question of what the conditioning factors of those instances were. More recently, the other obvious possibility has been assumed, namely that the correspondence between UM "/k/" and zero in the other scripts points to a distinct phoneme, "/h/", which would correspond to the word-initial phoneme "/h/" that is present in those other scripts. "/h/" (sometimes also called "/x/") is sometimes assumed to derive from *"", which would also explain zero in SM, AM, Ph in some instances where UM indicates /p/, e.g. "debel" > Khalkha "deel".

The palatal affricates *"č", *"čʰ" were fronted in Northern Modern Mongolian dialects such as Khalkha. was spirantized to in Ulaanbaatar Khalkha and the Mongolian dialects south of it, e.g. Preclassical Mongolian "kündü", reconstructed as''heavy', became Modern Mongolian (but in the vicinity of Bayankhongor and Baruun-Urt, many speakers will say ). Originally word-final *"n" turned into /ŋ/; if *' was originally followed by a vowel that later dropped, it remained unchanged, e.g.'became, but'became. After i-breaking, became phonemic. Consonants in words containing back vowels that were followed by'in Proto-Mongolian became palatalized in Modern Mongolian. In some words, word-final'was dropped with most case forms, but still appears with the ablative, dative and genitive.

Only foreign origin words start with the letter L and none start with the letter R.

The standard view is that Proto-Mongolic had '. According to this view,'and'were pharyngealized to and, then'and'were velarized to and. Thus, the vowel harmony shifted from a velar to a pharyngeal paradigm.'in the first syllable of back-vocalic words was assimilated to the following vowel; in word-initial position it became.'was rounded to when followed by '. VhV and VjV sequences where the second vowel was any vowel but "" were monophthongized. In noninitial syllables, short vowels were deleted from the phonetic representation of the word and long vowels became short.

E.g.'(' becomes,'disappears) >'(unstable "n" drops; vowel reduction) > /jama(n)/ 'goat'

and'(regressive rounding assimilation) >'(vowel velarization) > " (vowel reduction) > /oms-/ 'to wear'

This reconstruction has recently been opposed, arguing that vowel developments across the Mongolic languages can be more economically explained starting from basically the same vowel system as Khalkha, only with " instead of "*[e]". Moreover, the sound changes involved in this alternative scenario are more likely from an articulatory point of view and early Middle Mongol loans into Korean.

"-shaped bracket, and to the right of each such bracket, there are other medium-sized characters|"The Secret History of the Mongols" which goes back to a lost Mongolian script original is the only document that allows the reconstruction of agreement in social gender in Middle Mongol.]]

In the following discussion, in accordance with a preceding observation, the term "Middle Mongol" is used merely as a cover term for texts written in any of three scripts, Uighur Mongolian script (UM), Chinese (SM), or Arabic (AM).

The case system of Middle Mongol has remained mostly intact down to the present, although important changes occurred with the comitative and the dative and most other case suffixes did undergo slight changes in form, i.e., were shortened. The Middle Mongol comitative -"luγ-a" could not be used attributively, but it was replaced by the suffix -"taj" that originally derived adjectives denoting possession from nouns, e.g. "mori-tai" 'having a horse' became "mor'toj" 'having a horse/with a horse'. As this adjective functioned parallel to "ügej" 'not having', it has been suggested that a "privative case" ('without') has been introduced into Mongolian. There have been three different case suffixes in the dative-locative-directive domain that are grouped in different ways: -"a" as locative and -"dur", -"da" as dative or -"da" and -"a" as dative and -"dur" as locative, in both cases with some functional overlapping. As -"dur" seems to be grammaticalized from "dotur-a" 'within', thus indicating a span of time, the second account seems to be more likely. Of these, -"da" was lost, -"dur" was first reduced to -"du" and then to -"d" and -"a" only survived in a few frozen environments. Finally, the directive of modern Mongolian, -"ruu", has been innovated from "uruγu" 'downwards'. Social gender agreement was abandoned.

Middle Mongol had a slightly larger set of declarative finite verb suffix forms and a smaller number of participles, which were less likely to be used as finite predicates. The linking converb -"n" became confined to stable verb combinations, while the number of converbs increased. The distinction between male, female and plural subjects exhibited by some finite verbal suffixes was lost.

Neutral word order in clauses with pronominal subject changed from object–predicate–subject to subject–object–predicate, e.g.,

The syntax of verb negation shifted from negation particles preceding final verbs to a negation particle following participles; thus, as final verbs could no longer be negated, their paradigm of negation was filled by particles. For example, Preclassical Mongolian "ese irebe" 'did not come' vs. modern spoken Khalkha Mongolian "ireegüj" or "irsengüj"."For some Mongolian authors, the Mongolian version of their name is also given in square brackets, e.g., "Harnud [Köke]". Köke is the author's native name. It is a practice common among Mongolian scholars, for purposes of publishing and being cited abroad, to adopt a surname based on one's patronymic, in this example "Harnud"; compare Mongolian name."
