Common questions about Vietnamese
How do Vietnamese pronouns work?
Vietnamese 'pronouns' are kinship terms encoding age and social relationship. Anh = older brother (and what you call any older man). Em = younger sibling. Cô = aunt or younger woman. Chú = uncle. Ông = grandfather. Bà = grandmother. The choice is mutual — both speaker and listener pick relative kinship roles. Choosing wrong implies false intimacy or distance and is socially loud.
What are Vietnamese tones?
Northern Vietnamese has six tones: ngang (level), huyền (low falling), sắc (high rising), nặng (low broken), hỏi (low rising-falling), ngã (high broken). Each is marked with a diacritic on the vowel. Same consonants and vowels with different tones are unrelated words: ma (ghost), má (mother), mà (but), mả (grave), mã (horse), mạ (rice seedling). Southern dialects merge some tones.
Does Vietnamese have past, present, and future?
Vietnamese verbs never change for tense — they never change for anything. Time comes through pre-verbal particles or context. đã marks past or completed ('đã đi' = 'went'), đang marks ongoing ('đang đi' = 'is going'), sẽ marks future ('sẽ đi' = 'will go'), sắp marks imminent. Without a particle, the verb is unmarked — context decides.
Is Vietnamese SVO?
Yes — strict SVO. 'Tôi đọc sách' = 'I read book'. The verb sits between subject and object. Modifiers follow their head: 'người Việt' (Vietnamese person), 'sách hay' (good book) — the opposite of English. Topic-comment structure can front the topic ('sách này tôi đọc rồi' = 'this book, I've read'), but the underlying clause is still SVO.
Why do Vietnamese sentences sound 'choppy' to English ears?
Because every Vietnamese syllable is a meaningful unit, separately stressed and toned, and almost no syllable contracts into another. English compresses syllables ('I'm gonna' from 'I am going to'), reduces unstressed vowels to schwa, and uses sentence rhythm to group syllables into beats. Vietnamese keeps each syllable distinct and tonally marked, which is why it sounds rhythmically even rather than flowing.
