Historical Evolution
Vietnamese diverged from Viet-Muong, absorbing extensive Sino-Vietnamese vocabulary during millenniums of Chinese rule. French colonialism introduced romanization (Quốc ngữ), which replaced Chinese characters by the early 20th century. North–South political division left modest lexical and tonal differences still visible today.
Phonology
Vietnamese has six tones (including ngang, huyền, sắc, hỏi, ngã, nặng) on syllables with rigid C(G)V(C) structure. Vowel quality and final consonants (/p t k m n ŋ/) interact with tone. Regional splits (Hanoi vs Saigon) affect consonant mergers and vowel height.
Syntax
Vietnamese is SVO and analytic: no inflectional morphology for tense or number. Classifiers precede nouns in numeral phrases; serial verb constructions are common. Topic–comment organization and sentence-final particles encode aspect and stance.
