Kami menunggu sebelas menit di peron sebelum kereta tiba.

Both kami and kita can mean we, but they are not interchangeable.

• kami = we, but not including the person being spoken to
• kita = we, including the person being spoken to

So Kami menunggu... means the speaker and some other people were waiting, but the listener was not part of that group.

Menunggu means to wait.

It comes from the root word tunggu = wait.
Indonesian often adds the prefix meN- to form an active verb.

• tunggu = wait
• menunggu = to wait / to be waiting

This is very common in Indonesian. In a sentence like this, menunggu is the normal active verb form.

In Indonesian, 11 is sebelas, not satu belas.

Number pattern:

• sepuluh = 10
• sebelas = 11
• dua belas = 12
• tiga belas = 13

So sebelas menit simply means eleven minutes.

Indonesian nouns usually do not change form for plural after a number.

So:

• satu menit = one minute
• sebelas menit = eleven minutes

The noun stays menit either way.

This is normal in Indonesian. You do not need to add an ending like English -s.

Di is a preposition here, meaning in / at / on, depending on context.

• di peron = at the platform / on the platform

So di here marks location.

A very important point:

• di as a preposition is written separately: di peron
• di- as a passive verb prefix is written attached to the verb

Examples:

• di rumah = at home
• ditunggu = is waited for

Peron means a platform, especially a train platform.

So in this sentence, di peron refers to being at the railway platform while waiting for the train.

Sebelum means before.

It connects two parts of the sentence:

• Kami menunggu sebelas menit di peron = We waited eleven minutes on the platform
• sebelum kereta tiba = before the train arrived

So sebelum introduces the event that happened later.

Both tiba and datang can relate to arriving, but they are used a bit differently.

• tiba = to arrive, often focusing on the moment of arrival
• datang = to come / to arrive, often broader and more general

In a sentence about a train reaching the station, tiba sounds very natural.

So:

• kereta tiba = the train arrived

You could hear kereta datang in some contexts too, but tiba is a very common choice for scheduled arrivals.

Indonesian does not usually use articles like English the or a/an.

So:

• kereta can mean train or the train
• peron can mean platform or the platform

The exact meaning depends on context. In this sentence, English naturally uses the platform and the train, but Indonesian does not need separate words for that.

Yes. The sentence follows a very normal Indonesian pattern:

• Kami = subject
• menunggu = verb
• sebelas menit = duration
• di peron = location
• sebelum kereta tiba = time clause

So the structure is:

Subject + Verb + Duration + Location + Before-clause

This is a very natural order in Indonesian.

Yes, Indonesian has some flexibility.

For example, these are also possible:

• Kami menunggu di peron sebelas menit sebelum kereta tiba.
• Kami menunggu di peron selama sebelas menit sebelum kereta tiba.

But Kami menunggu sebelas menit di peron sebelum kereta tiba is perfectly natural.

Adding selama can make the duration feel more explicit:

• selama sebelas menit = for eleven minutes

Without selama, the sentence is still completely correct.

In Indonesian, a duration can often be stated directly without a separate word for for.

So:

• menunggu sebelas menit = wait eleven minutes / wait for eleven minutes

If you want, you can also say:

• menunggu selama sebelas menit

Both are correct, but omitting selama is very common.

Not necessarily.

The sentence only tells us that we waited eleven minutes on the platform before the train arrived. It does not by itself say whether the train was late, early, or exactly on time.

That kind of interpretation would depend on extra context.
