Để xem đã. Mai chắc được; bây giờ bận mất rồi.

It means something like Let me see first, Let me think about it first, or Hold on, let me check.

Word-for-word, để can mean to let / in order to, and xem means see / check / consider. But together, để xem is a very common expression used when someone wants a moment before deciding.

The đã at the end adds the sense of first / for the moment / before anything else.

So Để xem đã is not just about physically seeing something. It is a very natural way to say:

• Let me see first
• Let me check first
• I’ll think about it

Yes, đã often marks past time in other sentences, but here it is not a past marker.

In Để xem đã, sentence-final đã is a conversational particle that gives the meaning of first or for now. It softens the response and suggests that the speaker is not ready to answer immediately.

So here:

• đã does not mean already or past tense
• it means something more like first

Compare:

• Để xem đã. = Let me see first.
• Tôi đã xem rồi. = I already watched / I have seen it already.

Same word, different function.

Vietnamese often leaves out the subject when it is obvious from context.

In English, you usually need to say I’m busy or Let me see. In Vietnamese, if everyone already knows who is speaking or being referred to, the pronoun can be dropped.

So:

• Mai chắc được really means something like Tomorrow, I probably can / Tomorrow should probably work
• bây giờ bận mất rồi means (I’m) busy right now already / unfortunately busy right now

This omission is very normal and natural in Vietnamese conversation.

Yes. Mai here means tomorrow, and it is a shortened, very common spoken form of ngày mai.

Both are correct:

• mai = tomorrow
• ngày mai = tomorrow (a little fuller / more explicit)

In casual speech, people often just say mai.

Be careful not to confuse this with other words spelled similarly in writing without tone explanation, but in this sentence mai clearly means tomorrow.

Chắc means probably / likely / I think, and được here means okay / possible / can work.

So Mai chắc được means something like:

• Tomorrow will probably be okay
• Tomorrow should probably work
• I can probably do tomorrow

It sounds a little tentative, not 100% certain.

So the feeling is:

• not a firm promise
• but fairly positive

Correct. Được has several meanings in Vietnamese, and here it does not mean receive / get.

In this sentence, được means something like:

• be possible
• be okay
• work
• be acceptable

So:

• Mai chắc được = Tomorrow is probably possible / okay

This is a very common use of được in everyday Vietnamese.

For example:

• Hôm nay không được. = Today doesn’t work.
• Chiều mai được không? = Would tomorrow afternoon work?

It means (I’m) busy right now already or more naturally I’m tied up right now.

Breakdown:

• bây giờ = now / right now
• bận = busy
• mất = adds a nuance of something unfortunate, unintended, or contrary to what one might want
• rồi = already / now / has become

So bận mất rồi has a slightly stronger feeling than just bận rồi. It can suggest:

• I’ve ended up busy
• I’m unfortunately busy now
• I’m tied up already

Mất here is a nuance word that often adds a sense of:

• unfortunately
• to one’s regret
• ended up
• out of one’s control

It does not literally mean lose in this sentence.

Compare:

• bận rồi = busy already
• bận mất rồi = unfortunately busy already / ended up being busy already

So mất makes the statement sound a little more apologetic or regretful, which fits the situation well.

Rồi often marks a change of state or the idea of already.

In bây giờ bận mất rồi, it shows that the speaker is now in the state of being busy.

It can suggest:

• already
• now
• has become

So the feeling is not just busy, but busy now / already occupied now.

In conversation, rồi is extremely common after adjectives and verbs to show that something is now the case.

It is more like a soft postponement than a direct refusal.

The speaker is basically saying:

• Let me check first
• Tomorrow will probably work
• Right now I’m busy

So they are not saying a flat no. Instead, they are:

1. not committing immediately
2. suggesting a possible later time
3. giving a reason for not being available now

This is a very natural and polite way to respond in Vietnamese.

The two parts are closely connected:

• Để xem đã. = Let me check / let me think first.
• Mai chắc được; bây giờ bận mất rồi. = Tomorrow will probably work; right now I’m busy already.

The semicolon shows that the second part explains the situation more fully:

• the speaker cannot say yes right now
• they are busy at the moment
• tomorrow is more likely possible

In natural speech, this would usually be spoken with a pause rather than thought of as formal punctuation.

Yes.

This version is quite natural and conversational. A more explicit version might be:

• Để tôi xem đã. Ngày mai chắc được, bây giờ tôi bận mất rồi.

That includes tôi and ngày mai, which makes it clearer and slightly more explicit.

A simpler casual version could be:

• Để xem đã. Mai chắc được, giờ bận rồi.

So the original sentence is natural spoken Vietnamese, with some elements omitted because they are understood from context.
