Kami boleh meregangkan badan dan berehat; lagipun, semua berpeluh.

In Malay, kami and kita both translate as 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 boleh meregangkan badan dan berehat means the speaker is talking about their own group, but not necessarily including the listener. If the listener were part of the group, kita would usually be the better choice.

Here, boleh means something like can, are able to, or may.

Depending on context, boleh can express:

• ability: can
• permission: may / are allowed to
• possibility: could

In this sentence, it most likely means we can or we may, in the sense of it makes sense for us to or we’re allowed to stretch and rest.

Meregangkan badan literally means to stretch the body.

It is a very natural Malay expression for stretching after exercise or physical activity. English often just says stretch, but Malay commonly uses the fuller phrase meregangkan badan.

Breaking it down:

• regang = stretch / taut
• meregangkan = to stretch something
• badan = body

So the phrase is literally stretch the body, but naturally translated as stretch or do some stretching.

The word meregangkan is built from the root regang.

The affixes meN- and -kan often make a verb that means to do something to something or to cause something to become a certain way.

So:

• regang = stretched / taut / stretch
• meregangkan = to stretch something

In this sentence, the thing being stretched is badan. That is why meregangkan badan works like a transitive verb phrase: to stretch the body.

Malay often leaves this kind of thing understood from context.

Even though badan is singular in form, meregangkan badan naturally means that each person is stretching their own body. Malay does not always mark plural nouns the way English does.

So badan here does not sound odd. It is a normal, idiomatic way to say stretch our bodies or simply stretch.

Rehat is the base word meaning rest or a break.
Berehat is the verb meaning to rest.

So:

• rehat = rest, break
• berehat = to rest

Examples:

• Saya perlukan rehat. = I need a rest.
• Saya mahu berehat. = I want to rest.

In your sentence, dan berehat means and rest.

Lagipun means after all, besides, or anyway.

It introduces a reason or added justification for what was just said. In this sentence, it explains why stretching and resting is reasonable:

• Kami boleh meregangkan badan dan berehat
• lagipun, semua berpeluh

So the sense is: We can stretch and rest; after all, everyone is sweating.

Malay often leaves out words that are already clear from context.

In lagipun, semua berpeluh, the word semua already acts as the subject, meaning everyone or all of us / all of them, depending on context. So no extra pronoun is needed.

Malay is generally comfortable with this kind of compact structure.

Semua usually means all or everyone.

In this sentence, because there is no noun after it, semua stands on its own and means something like:

• everyone
• all of us
• all of them

The exact meaning depends on context. If the speaker is talking about their group, semua berpeluh could naturally mean everyone is sweating or we’re all sweating.

Berpeluh means to sweat or to be sweating.

It comes from:

• peluh = sweat
• berpeluh = to sweat / be sweaty

The prefix ber- often forms intransitive verbs in Malay. In many cases, it gives the sense of having, wearing, doing, or being in a state connected with the root word.

So berpeluh literally suggests being in a state of sweat, which English expresses as sweating.

Malay verbs do not change form for tense the way English verbs do. There is no special verb ending here to show present or future.

So boleh meregangkan could mean:

• can stretch
• can now stretch
• can go stretch
• may stretch

And semua berpeluh could mean:

• everyone is sweating
• everyone’s sweating
• everyone got sweaty, depending on context

The time reference usually comes from context, not from verb inflection.

The semicolon is mainly a writing choice. It links two closely related ideas:

• Kami boleh meregangkan badan dan berehat
• lagipun, semua berpeluh

It shows that the second part explains or supports the first part. A full stop or even a comma might also appear in less formal writing, but the semicolon makes the connection especially clear.
