Learning how to ask questions is an essential step in your Vietnamese journey.

One of the most common ways to confirm information is by using the phrase phải không.

This simple phrase instantly turns any regular statement into a yes or no question.

It works exactly like adding “right?” or “isn’t it?” to the end of an English sentence.

I’ll show you exactly how to use phải không to communicate more naturally.

The meaning of phải không

To understand how this phrase works, it helps to look at the individual words.

The word phải means “right” or “correct” in Vietnamese.

The word không is the standard word for “no” or “not”.

When you put them together, phải không literally translates to “correct or not?”.

You use this phrase when you already think something is true, but you want the other person to confirm it.

It takes the guesswork out of asking complex questions.

How to form questions with phải không

Forming a question with this phrase is incredibly easy.

You simply take a normal, declarative sentence and add phải không to the very end.

You don’t need to change the word order of the original sentence.

Here’s the basic formula:

Here are a few examples to show you how this works in real conversations.

How to answer a phải không question

When someone asks you a phải không question, they’re expecting a direct yes or no.

To say “yes” (that’s correct), you simply reply with phải or đúng rồi.

If you’re speaking to someone older than you, you should add a polite particle like dạ or vâng at the beginning of your sentence.

To say “no” (that’s incorrect), you reply with không phải.

You can also provide the corrected information immediately after saying no.

Regional variations of phải không

Vietnamese pronunciation varies heavily depending on the region.

In Northern Vietnam, people pronounce the word không very clearly.

In Southern Vietnam, spoken language tends to be a bit more relaxed.

Southern speakers usually pronounce phải không as phải hông or phải hong.

You’ll hear this “h” sound instead of the “kh” sound very frequently in Ho Chi Minh City.

Additionally, when Vietnamese people text each other, they almost always abbreviate the word không.

You’ll commonly see it typed as phải ko or phải k in casual daily messages.
