Mandarin usually puts the time expression before the main verb.

So the pattern here is:

subject + approximation word + time + verb

• 我们 = we
• 大概 = about / approximately
• 八点 = eight o’clock
• 到 = arrive

So 我们大概八点到 literally follows the Mandarin logic We / approximately / eight o’clock / arrive.

If you put 到 before 八点, it would sound like arrive until eight o’clock or suggest a different structure, not the intended meaning here.

Here, 大概 means about, around, or approximately.

It tells you that 八点 is not exact. So the arrival time is roughly eight o’clock, not necessarily exactly 8:00.

A useful thing to know: 大概 can also mean probably in other sentences, depending on context. But in this sentence, because it comes right before a time expression, it clearly means approximately.

When telling clock time in Mandarin, you normally use:

number + 点

So:

• 八点 = eight o’clock
• 三点 = three o’clock
• 十点 = ten o’clock

点 is the word used for o’clock in time expressions.

Without 点, 八 would just mean eight, not eight o’clock.

Yes, 到 often means to arrive at or to reach, and it can be followed by a destination:

• 到学校 = arrive at school
• 到北京 = arrive in Beijing

But in everyday Mandarin, 到 can also be used by itself when the destination is already understood or not important.

So 我们大概八点到 means something like:

• We’ll arrive around eight
• We’ll get there around eight

The place is left unstated because it is already clear from context.

Mandarin does not mark tense the same way English does.

This sentence has no special tense marker, so the time reference comes from context. In many situations, it will be understood as future:

• We’ll arrive around eight.

But depending on the conversation, it could also mean something like a scheduled or habitual arrival time.

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

• 今天 = today
• 明天 = tomorrow
• 晚上 = in the evening

For example:

• 我们明天大概八点到。 = We’ll arrive around eight tomorrow.

Yes, very often you can.

Mandarin frequently drops the subject when it is already obvious from context. So in conversation, people might simply say:

大概八点到。

That still means (We/I/they) will arrive around eight, depending on the situation.

Including 我们 makes the sentence clearer and more explicit, especially for learners or when the speaker wants to emphasize we.

It is much more natural to say:

我们大概八点到

because 大概 normally comes before the part it modifies, here 八点.

If you want to place the idea of approximation after the time, Mandarin usually uses another pattern, such as:

• 我们八点左右到。
• 我们差不多八点到。

So while learners may want to say 我们八点大概到, that is not the standard or most natural choice.

Yes. A few very common alternatives are:

• 八点左右 = around eight
• 差不多八点 = almost / about eight
• 大约八点 = approximately eight

So you could also say:

• 我们八点左右到。
• 我们差不多八点到。
• 我们大约八点到。

They are all natural. 大概八点 is also very common and conversational.

我们 is pronounced wǒmen.

• 我 = third tone
• 们 = usually a neutral tone

So it is not normally pronounced as wǒmén with a strong second tone. The second syllable is light and unstressed.

A natural rhythm is:

• wǒmen dàgài bādiǎn dào

with 们 said lightly.

Not really, because 大概 explicitly makes the time approximate.

So the sentence means:

• around eight
• about eight
• approximately eight

If you want to say exactly at eight, you would usually remove 大概:

• 我们八点到。

That means We arrive at eight or We’ll arrive at eight, depending on context.
