Vietnamese Simple Grammar: Sentence Structure

You've probably heard that Vietnamese grammar is difficult. It isn't. In fact, if you speak English, the core structure of a Vietnamese sentence is going to feel incredibly familiar. You don't have to worry about conjugating verbs, changing word endings for plurals, or matching genders. You just need to know what order the words go in.

A lot of textbooks overcomplicate this, but the truth is, the Vietnamese language is incredibly logical. It doesn't waste time on grammatical rules that don't add meaning to the sentence. In this guide, we'll break down the absolute basics of how to build a Vietnamese sentence, focusing specifically on the Southern style you'll hear every day in Saigon.

Master these foundational patterns, and you'll be able to construct thousands of sentences and make yourself understood anywhere in Southern Vietnam.

The foundation: Subject + Verb + Object (S-V-O)

Let's start with the best news: Vietnamese uses the exact same basic word order as English. You put the person doing the action (the Subject), followed by the action itself (the Verb), and then the thing receiving the action (the Object).

In Vietnamese, you can often just drop words right into the English slots. As long as you know the vocabulary, the sentence practically builds itself. You don't have to learn a completely new way of thinking about how events unfold, which is very comforting for beginners.

Adverbs that modify the verb — words that describe how or how much you do something — generally go after the verb, or if there's an object, after the object. You wouldn't say "I love a lot you" in English, and you don't say it in Vietnamese either.

Adjectives go after the noun

In English, we say "a beautiful voice," "a big house," or "hot coffee." The adjective leads the way. In Vietnamese, the core noun comes first, and the adjective follows it. It's "voice beautiful," "house big," and "coffee hot." You name the thing you're talking about, and then you describe it. This lets people immediately know the subject.

If you want to add an intensifier like "very" (rất), it goes immediately before the adjective, just like in English. So "very beautiful" is rất đẹp. In Saigon, you will also hear people use quá or lắm at the very end of the sentence to mean "very", as in đẹp quá! Learn more about describing things with intensifiers here.

Time words: Beginning or end

When you want to say when something happens — using words like today (hôm nay), tomorrow (ngày mai), or next week (tuần sau) — you can put it at the very beginning of the sentence, or at the very end of the sentence. You can't go wrong with either choice in spoken Vietnamese.

Both are perfectly natural and used constantly in Saigon. The only rule is: don't stick the time word right in the middle between the subject and the verb, like you might do in some English contexts.

Putting the time word at the very beginning shines a bit of a spotlight on when the action is taking place, making the timing the most important part of the sentence. Putting it at the end emphasises the action itself.

Saying "not" with không

To make a sentence negative, you don't need helping verbs like "don't" or "didn't". You just take the word không (which means "no" or "not") and place it directly before the verb or the adjective you want to negate. It really is that straightforward.

In spoken Southern Vietnamese, people almost always pronounce không as hông. It sounds softer and flows much better in casual conversation.

If you want to say you "haven't yet" done something, instead of using không, you use chưa before the verb. For example, Tui chưa ăn means "I haven't eaten yet." Learn more ways to say no.

Asking questions: không, chưa, gì, đâu

Vietnamese doesn't rearrange the sentence to form a question like English does. Instead, you keep the normal sentence structure and either tack a question word onto the end or replace the noun with a question word. This is brilliant because you only need to learn one sentence pattern for both statements and questions.

Yes/No questions

To ask a yes/no question, put không (or hông) at the end of the sentence. If you're asking if something has happened yet, put chưa at the end. That's all there is to it.

What and Where

To ask "what" (gì) or "where" (đâu), you just replace the object or location in the sentence with the question word. So instead of saying "I eat rice", you say "I eat what?". Learn more about asking questions here.

Time travel: đã, đang, sẽ

Because Vietnamese verbs don't conjugate, you don't have to learn past, present, or future tense forms of a verb. "Eat" is always ăn. If the context makes it obvious when something happens, you don't need to add anything. This saves you hundreds of hours of memorisation.

If you do need to clarify the tense, you just place a small marker right before the verb: đã for past, đang for present continuous (-ing), and sẽ for future. Read our full guide on Vietnamese tenses here.

A quick word on classifiers (cái, con)

When you count or point at a specific object in Vietnamese, you usually need a "classifier" before the noun. You can think of this as categorising the object before you talk about it. The two most common are cái (for inanimate objects) and con (for animals). Dive deeper into classifiers here.
