Vietnamese languages primarily refer to the languages spoken in Vietnam, with the most prominent being Vietnamese, the official language. Vietnamese belongs to the Austroasiatic language family and is known for its tonal nature, meaning that the pitch used when pronouncing a word can change its meaning. In addition to Vietnamese, there are several minority languages spoken by various ethnic groups in Vietnam, such as Tày, Thái, and Mường. These languages contribute to the rich linguistic diversity of the country, reflecting its complex cultural heritage and the coexistence of different communities.
