The primary language spoken in Vietnam is Vietnamese. It belongs to the Austroasiatic language family and is the mother tongue of approximately 86% of the population. There are several dialects of Vietnamese, with Northern, Central, and Southern variations reflecting regional differences in pronunciation, vocabulary, and expressions. The language uses the Romanized script called "Quốc Ngữ," developed in the 17th century, which replaced the traditional Chinese characters previously used. Understanding Vietnamese provides valuable insights into the rich culture, history, and traditions of Vietnam.
