Vietnamese is the national, official language of Vietnam. It is the native language of Vietnamese people, and of about three million Vietnamese residing elsewhere. It also is spoken as a first or second language by many ethnic minorities of Vietnam. It is part of the Austroasiatic language family of which it has, by far, the most speakers . Much of Vietnamese vocabulary has been borrowed from Chinese, and it formerly used a modified Chinese writing system and given vernacular pronunciation. As a byproduct of French colonial rule, Vietnamese was influenced by the French language; the Vietnamese alphabet in use today is a Latin alphabet with additional diacritics for tones, and certain letters.
