Vietnamese :

Vietnamese (tiếng Việt, or less commonly Việt ngữ) is the national and official language of Vietnam. It is the mother tongue of 86% of Vietnam's population, and of about three million overseas Vietnamese. It is also spoken as a second language by many ethnic minorities of Vietnam. It is part of the Austroasiatic language family, of which it has the most speakers by a significant margin (several times larger than the other Austroasiatic languages put together). As with Korean and Japanese, much vocabulary has been borrowed from Chinese, most notably Cantonese, especially words that denote abstract ideas (in the same way European languages borrow from Latin and Greek), and it was formerly written using the Chinese writing system, albeit in a modified format and was given vernacular pronunciation. As a byproduct of French colonial rule, the language displays some influence from French, and the Vietnamese writing system in use today is an adapted version of the Latin alphabet, with additional diacritics for tones and certain letters.

As the national language of the majority ethnic group, Vietnamese is spoken throughout Vietnam by the Vietnamese people, as well as by ethnic minorities. It is also spoken in overseas Vietnamese communities, most notably in the United States, where it has more than one million speakers and is the seventh most-spoken language (it is 3rd in Texas, 4th in Arkansas and Louisiana, and 5th in California). In Australia, it is the sixth most-spoken language.

Vietnamese was identified more than 150 years ago to be part of the Mon-Khmer branch of the Austroasiatic language family (a family that also includes Khmer, spoken in Cambodia, as well as various tribal and regional languages, such as the Munda and Khasi languages spoken in eastern India, and others in southern China). Later, Mường was found to be more closely related to Vietnamese than other Mon-Khmer languages, and a Việt-Mường sub-grouping was established. As data on more Mon-Khmer languages were acquired, other minority languages (such as Thavưng, Chứt languages, Hung, etc.) were found to share Việt-Mường characteristics, and the Việt-Mường term was renamed to Vietic. The older term Việt-Mường now refers to a lower sub-grouping (within an eastern Vietic branch) consisting of Vietnamese dialects, Mường dialects, and Nguồn (of Quảng Bình Province).
