Chúng tôi đến đảo.

Chúng tôi means we, but specifically we excluding the listener.

That is one of the most important things English speakers have to learn about Vietnamese pronouns:

• chúng tôi = we, but not you
• chúng ta = we, including you

So if I say Chúng tôi đến đảo, I am talking about my group, but I am not including the person I’m speaking to.

Chúng tôi is also fairly neutral and standard in style. In casual speech, you may also hear forms like tụi tôi or bọn tôi.

Đến is a very flexible verb. It basically expresses the idea of reaching a place.

Depending on context, English may translate it as:

• come to
• go to
• arrive at

That is why a sentence with đến may not match one single English verb every time.

In Chúng tôi đến đảo, the core idea is that the group comes/goes/arrives at the island. The exact English choice depends on viewpoint and context.

Because Vietnamese does not need a separate preposition here the way English often does.

The pattern is simply:

• subject + đến + place

So:

• chúng tôi = subject
• đến = movement toward / arrival at
• đảo = destination

In English, we usually need to or at, but in Vietnamese đến already does that job.

Vietnamese does not use articles like a, an, and the in the same way English does.

So đảo can mean:

• an island
• the island
• simply island as a destination

The exact meaning depends on context.

If Vietnamese wants to be more specific, it can add other words, for example:

• hòn đảo đó = that island
• một hòn đảo = an island

But in your sentence, đảo by itself is completely normal.

No. Vietnamese verbs do not change form for tense the way English verbs do.

So đến stays đến whether the action is past, present, or future. Time is usually understood from:

• context
• time words
• aspect markers

For example:

• Hôm qua chúng tôi đến đảo. = yesterday
• Bây giờ chúng tôi đang đến đảo. = now / in progress
• Ngày mai chúng tôi sẽ đến đảo. = future

Without extra context, Chúng tôi đến đảo is tense-neutral.

Đảo by itself is fine.

Vietnamese often uses the bare noun:

• đảo = island

You can also say:

• hòn đảo

Here, hòn is a classifier often used for things like islands, rocks, and some other natural objects.

Very roughly:

• đảo = perfectly normal, common
• hòn đảo = a bit more explicit, sometimes more descriptive

So your sentence is grammatical and natural as written.

A rough guide:

• chúng: roughly like choong, with a rising tone
• tôi: roughly like toy, with a level tone
• đến: roughly like den or dayn, with a rising tone
• đảo: roughly like dao, but with a dipping/questioning tone

A few useful pronunciation notes:

• đ is pronounced like an English d
• ch is not exactly the same as English ch, but that is a reasonable starting point
• tones matter a lot in Vietnamese

The tones here are:

• chúng = sắc tone
• tôi = ngang tone
• đến = sắc tone
• đảo = hỏi tone

Yes, in this sentence it is quite similar.

The structure is:

• Chúng tôi = subject
• đến = verb
• đảo = place/destination

So it follows a simple Subject + Verb + Object/Complement pattern.

That said, Vietnamese often differs from English in other areas, especially with:

• time expressions
• classifiers
• pronouns
• aspect markers

But this particular sentence is fairly straightforward in its word order.

To make it negative, add không before the verb:

• Chúng tôi không đến đảo.

To ask a yes/no question, common patterns include:

• Chúng tôi đến đảo à?
• Chúng tôi có đến đảo không?

The second pattern is especially useful for learners because it is very clear:

• có + verb + không?

So:

• Chúng tôi có đến đảo không? = Do we come/go to the island? / Are we arriving at the island? depending on context.
