Số dư trong tài khoản còn đủ.

Số dư means balance, especially the amount of money remaining in an account.

• số = number, amount
• dư = surplus, remainder, what is left over

Together, số dư is the normal Vietnamese term for an account balance.

trong tài khoản means in the account and it describes which balance we are talking about.

So:

• số dư = the balance
• trong tài khoản = in the account

Vietnamese often puts descriptive phrases after the noun, so số dư trong tài khoản literally looks like balance in the account.

You can think of it as one noun phrase:

• số dư trong tài khoản = the balance in the account

Here, còn means still or remains.

So còn đủ means is still enough or remains sufficient.

This word adds the idea that the balance has not run out yet. For example, it suggests something like:

• there was enough before, and
• there is enough now as well

Without còn, the sentence would simply state that the balance is enough. With còn, it emphasizes that it is still enough.

đủ means enough or sufficient.

In this sentence, it describes the balance. So the sentence says that the account balance is sufficient.

Very often, đủ can be followed by more information:

• đủ tiền = enough money
• đủ thời gian = enough time
• đủ để trả = enough to pay

In Số dư trong tài khoản còn đủ, the thing it is enough for is left unstated because the context already makes it clear.

Vietnamese often does not use a verb like to be when an adjective is the main predicate.

In English, you say:

• The balance is enough.

In Vietnamese, you can simply say:

• Số dư ... đủ.

Here, đủ works like the main predicate of the sentence, so no separate word for is is needed.

That is very normal in Vietnamese.

A simple way to break it down is:

• Số dư trong tài khoản = the balance in the account
• còn đủ = is still enough

So the pattern is:

• [noun phrase] + [predicate]

More literally:

• Balance in account still enough

More natural English:

• The balance in the account is still sufficient.
• There is still enough balance in the account.

Vietnamese often leaves out information that is understood from context.

So Số dư trong tài khoản còn đủ usually appears in a situation where everyone already knows what the money is for, such as:

• paying for a purchase
• making a transfer
• covering a fee
• maintaining minimum balance

If you want to make it explicit, Vietnamese can say:

• Số dư trong tài khoản còn đủ để thanh toán.
  = The balance in the account is still enough to make the payment.

• Số dư trong tài khoản còn đủ tiền.
  = The balance in the account still has enough money.

Not always. Tài khoản is a general word for account.

Depending on context, it can mean:

• a bank account
• an online account
• a user account
• an e-wallet account

In this sentence, because of số dư (balance), it most naturally suggests a financial account, such as a bank account or payment account.

Yes, often you can.

• số dư tài khoản = account balance
• số dư trong tài khoản = balance in the account

Both are natural, but they feel slightly different:

• số dư tài khoản is more compact and label-like, common in banking or formal contexts
• số dư trong tài khoản feels a little more like everyday phrasing, emphasizing the money inside the account

So both are possible, depending on style and context.

Yes, vẫn đủ can also work, but the nuance is a little different.

• còn đủ = still enough, with a sense of remaining
• vẫn đủ = still enough, with a sense of continuing to be true

So:

• Số dư trong tài khoản còn đủ sounds very natural when talking about remaining funds.
• Số dư trong tài khoản vẫn đủ is also possible, but còn fits especially well when money may decrease over time.

Yes. It is complete and natural, especially in situations like banking, payments, or app notifications.

It may sound a little concise or functional, which is normal in those contexts. For example, a banking app or cashier system might use wording like this.

In everyday speech, a person might also say something slightly fuller, such as:

• Số dư trong tài khoản vẫn còn đủ.
• Tài khoản còn đủ tiền.

But your original sentence is perfectly normal.

A rough pronunciation guide is:

• Số → like soh with a rising-creaky tone
• dư → roughly zư in northern Vietnamese, yư/dư in southern speech
• trong → like chawng/tchong depending on accent
• tài khoản → tai khoan
• còn → cawn with a falling tone
• đủ → doo with a dipping-rising tone

A very rough English-style approximation is:

soh zư chong tai-khoan cawn doo

But tone and vowel quality matter a lot in Vietnamese, so it is best to listen to native audio if possible.

Not very naturally.

A word-for-word gloss would be something like:

• số dư = balance
• trong tài khoản = in the account
• còn = still/remains
• đủ = enough

So literally:

• Balance in the account still enough

Natural English would be:

• The balance in the account is still enough.
• There is still enough money in the account.
• The account still has enough balance/funds.

The best translation depends on context.
