Vietnamese (Tiếng Việt) is an Austroasiatic language from Vietnam where it is the national and official language. Vietnamese is spoken natively by around 85 million people, several times as many as the rest of the Austroasiatic family combined. It is the native language of the Vietnamese (Kinh) people, as well as a second language or first language for other ethnic groups in Vietnam. Like many other languages in Southeast Asia and East Asia, Vietnamese is an analytic language with phonemic tone. It has head-initial directionality, with subject–verb–object order and modifiers following the words they modify. It also uses noun classifiers. Its vocabulary has had significant influence from Chinese and some from French. Vietnamese was historically written using Chữ Nôm, a logographic script using Chinese characters (Chữ Hán) to represent Sino-Vietnamese vocabulary and some native Vietnamese words, together with many locally invented characters to represent other words. The Vietnamese alphabet (Chữ Quốc Ngữ) which is based on the Latin script, was officially adopted during French rule of Vietnam. It uses digraphs and diacritics to mark tones and some phonemes. Early linguistic work some 150 years ago (Logan 1852 and Schmidt 1905) classified Vietnamese as belonging to the Mon–Khmer branch of the Austroasiatic language family (which also includes the Khmer language spoken in Cambodia, as well as various smaller and/or regional languages, such as the Munda and Khasi languages spoken in eastern India, and others in Laos, southern China and parts of Thailand). Later, Mường was found to be more closely related to Vietnamese than other Mon–Khmer languages, and a Viet–Muong subgrouping was established, also including Thavung, Chut, Cuoi, etc. The term "Vietic" was proposed by Hayes (1992), who proposed to redefine Viet–Muong as referring to a subbranch of Vietic containing only Vietnamese and Mường.
