Vietnamese Sentence Structure: Grammar Basics for Beginners
Vietnamese follows Subject-Verb-Object like English, but adjectives follow nouns and classifiers count things. Learn the core sentence patterns.
Vietnamese uses Subject-Verb-Object (SVO), like English. Two key differences: adjectives come after the noun (nhà đẹp = "house pretty"), and classifiers sit between a number and a noun (ba con mèo = "three cats"). Verbs and nouns never change form.
Because Vietnamese has no conjugation or plurals, "grammar" is really just word order plus a few small connecting words. Here are the patterns you'll use constantly.
Basic word order (SVO)
Vietnamese sentences run Subject → Verb → Object, exactly like English:
- Tôi (I) ăn (eat) cơm (rice).
- Cô ấy (She) đọc (reads) sách (a book).
If you can build an English sentence, you already know the Vietnamese skeleton.
Adjectives follow nouns
The big reversal: the describing word comes after the noun.
| English | Vietnamese | Literal |
|---|---|---|
| pretty house | nhà đẹp | house pretty |
| hot coffee | cà phê nóng | coffee hot |
| Vietnamese language | tiếng Việt | language Viet |
Once you can describe something, the next step is comparing it: see Vietnamese comparatives for hơn (more) and nhất (most).
Classifiers
To count things, you usually need a classifier between the number and the noun:
| Classifier | Used for | Example |
|---|---|---|
| con | animals | hai con chó (two dogs) |
| cái | objects/things | ba cái bàn (three tables) |
| người | people | bốn người bạn (four friends) |
| quả / trái | fruit | một quả táo (one apple) |
There are many more, and which one to use has its own logic. Full guide with a matching drill: Vietnamese classifiers.
The pronoun system
Vietnamese has no neutral "you." You pick a pronoun based on age and gender, anh, chị, em, cô, chú, the same words used in greetings and family terms. Tôi is a neutral "I" that's safe in most situations.
Asking questions
- Yes/no: add không? at the end, Bạn khỏe không? (Are you well?).
- Confirm: phải không?, Đúng phải không? (Right?).
- Question words: gì (what), ai (who), ở đâu (where), khi nào (when), bao nhiêu (how much). Where each one sits in the sentence follows a pattern, see the full guide to Vietnamese question words.
Negation & tense
- Negate with không before the verb: Tôi không hiểu (I don't understand).
- Tense uses đã / đang / sẽ before the verb, no conjugation. See the full guide to Vietnamese verb tenses, part of why grammar is easier than it looks.
Put it together and you can already make hundreds of sentences. Next, expand your vocab with phrases and the full roadmap.

Common questions
Vietnamese uses Subject-Verb-Object (SVO), like English. The main differences are that adjectives come after the noun, and classifiers sit between a number and a noun.
After. Vietnamese says 'nhà đẹp' (house pretty) rather than 'pretty house.' The describing word follows the thing it describes.
Classifiers are small counting words placed between a number and a noun, such as 'con' for animals, 'cái' for objects, and 'người' for people, e.g. 'ba cái bàn' (three tables).
For yes/no questions, add 'không?' at the end (Bạn khỏe không? = Are you well?). For others, use question words like 'gì' (what), 'ở đâu' (where), and 'khi nào' (when).
