Tôi đợi vài phút.

In Vietnamese, you often do verb + duration without needing a separate word for for.

So:

• đợi vài phút = wait for a few minutes

English needs for, but Vietnamese usually does not in this pattern.

Other examples:

• học hai tiếng = study for two hours
• ngủ một lúc = sleep for a while

Vài means a few or several. It refers to a small, indefinite number.

So vài phút means:

• a few minutes
• several minutes

It does not give an exact number.

Related words:

• một vài = a few, a small number of
• mấy = a few / some, but can also mean how many in questions, depending on context

No. Phút is a time unit noun meaning minute, not a classifier in this sentence.

In Vietnamese, units of time like these usually come directly after the number or quantity word:

• một phút = one minute
• vài phút = a few minutes
• ba giờ = three hours

So you do not need a separate classifier between vài and phút.

The word order is:

• Tôi = subject
• đợi = verb
• vài phút = duration phrase

So the pattern is:

Subject + Verb + Duration

That is very common in Vietnamese.

By itself, Vietnamese often does not mark tense the way English does. The time meaning usually comes from context.

So Tôi đợi vài phút could be understood as:

• I wait a few minutes
• I’m waiting for a few minutes
• I waited a few minutes

depending on the situation.

If you want to make the time clearer, Vietnamese can add words like:

• đã for past: Tôi đã đợi vài phút.
• đang for ongoing action: Tôi đang đợi.
• sẽ for future: Tôi sẽ đợi vài phút.

Yes. Vietnamese can leave the object unstated if it is already clear from context.

So Tôi đợi vài phút is natural if the listener already knows what you are waiting for, or if the point is simply that you waited.

If you want to include the object, you can say:

• Tôi đợi bạn vài phút. = I waited for you for a few minutes.
• Tôi đợi xe buýt vài phút. = I waited for the bus for a few minutes.

Both đợi and chờ mean to wait, and in many situations they are interchangeable.

So both of these are natural:

• Tôi đợi vài phút.
• Tôi chờ vài phút.

Which one sounds more natural can depend on region, habit, and personal preference. As a learner, it is good to recognize both.

Tôi is a common and safe way to say I, especially in neutral, formal, or textbook-style Vietnamese.

However, everyday Vietnamese often uses kinship terms or relationship-based pronouns instead, depending on age and social context. For example, a speaker might say em, anh, chị, or con instead of tôi.

So tôi is correct and useful, but real-life speech may use other self-references.

Sometimes yes. Vietnamese often drops the subject when it is obvious from context.

So in conversation, if everyone already knows you are talking about yourself, you might just say:

• Đợi vài phút.

But if you are learning, keeping tôi is helpful because it makes the sentence clear and complete.

A few useful points:

• đ is not the same as plain d in Vietnamese spelling.
• The vowel part in đợi is roughly like ơi plus a final glide.
• The marked tone is important.

For a learner, the main thing is:

• learn đ as its own consonant
• pay attention to the tone mark on ợ
• do not pronounce it like English doit or doyt

The best way to learn it accurately is by listening to native audio and repeating it, since tone and vowel quality matter a lot in Vietnamese.

Usually you put it right after the verb, and the duration comes after that.

Pattern: Subject + Verb + Object + Duration

Examples:

• Tôi đợi bạn vài phút. = I waited for you for a few minutes.
• Tôi đợi anh ấy vài phút. = I waited for him for a few minutes.

So Tôi đợi vài phút is shorter, while Tôi đợi bạn vài phút is more specific.
