Kalaupun hujan malam ini, kami tetap akan berkhemah.

Kalaupun means even if in this sentence.

It is built from:

• kalau = if
• pun = a particle that adds emphasis, often giving the sense of even

So Kalaupun hujan malam ini means Even if it rains tonight.

Compared with plain kalau, kalaupun sounds a bit stronger and more concessive: the speaker is saying that the result in the main clause will still happen despite that condition.

In Malay, hujan can function as both:

• a noun: rain
• a weather predicate: to rain / be raining

So hujan malam ini naturally means it rains tonight or it is rainy tonight, depending on context.

Malay often does not need a separate dummy subject like English it.
English says it is raining, but Malay simply says hujan.

Malay usually does not use a dummy subject like English it for weather expressions.

So English:

• It is raining
• It will rain tonight

becomes simply:

• Hujan
• Hujan malam ini

This is very normal in Malay.

Tetap means still, nevertheless, all the same, or remain steadfast depending on context.

In this sentence, it shows that the decision does not change:

• kami tetap akan berkhemah = we will still go camping

So the sentence is not just about a future action. It also expresses determination or persistence.

Without tetap, the sentence would simply say:

• Kalaupun hujan malam ini, kami akan berkhemah
  = Even if it rains tonight, we will go camping

That is correct, but tetap adds the sense of we are sticking with the plan anyway.

They do different jobs:

• akan marks future time: will
• tetap marks persistence or unchanged intention: still / nevertheless

So:

• akan berkhemah = will camp
• tetap akan berkhemah = will still camp

They work together naturally.

Berkhemah means to camp or to go camping.

It comes from:

• khemah = tent
• ber- = a common verb-forming prefix

So berkhemah literally has the idea of being in a tent / doing a tent-related activity, which in normal English is simply camp.

Berkhemah by itself is enough to mean camp or go camping.

So these are both possible:

• kami akan berkhemah = we will camp / go camping
• kami akan pergi berkhemah = we will go camping

Adding pergi can make the movement aspect clearer, but it is not necessary.

Malam ini means tonight.

In Malay, time expressions are often placed after the verb or predicate:

• hujan malam ini = it rains tonight
• kami akan berkhemah malam ini = we will camp tonight

This word order is very normal. Malay is generally flexible with time expressions, but this placement is one of the most common patterns.

Malay has two common words for we:

• kami = we, excluding the listener
• kita = we, including the listener

So kami tetap akan berkhemah means the speaker’s group will go camping, but the listener is not part of that group.

If the listener is included, it would be:

• Kalaupun hujan malam ini, kita tetap akan berkhemah.

This is a very important distinction in Malay.

Yes, but the nuance changes.

• Kalau hujan malam ini, kami tetap akan berkhemah.
  = If it rains tonight, we will still camp.

• Jika hujan malam ini, kami tetap akan berkhemah.
  = also correct, but jika sounds a bit more formal than kalau

• Kalaupun hujan malam ini, kami tetap akan berkhemah.
  = Even if it rains tonight, we will still camp

So kalaupun is the best choice when you want the concessive meaning even if.

The comma is helpful because the sentence begins with a conditional clause:

• Kalaupun hujan malam ini, = subordinate clause
• kami tetap akan berkhemah. = main clause

The comma makes the structure easier to read. In informal writing, Malay punctuation can be a bit flexible, but this comma is appropriate and natural.

Yes, Malay often allows that kind of reordering, but it is less natural in this case.

The original version:

• Kalaupun hujan malam ini, kami tetap akan berkhemah.

is clearer because it presents the condition first and then the main result.

Putting the conditional clause at the end is possible, but the sentence feels more elegant and standard with the original order.

It is fairly neutral and natural.

• kalaupun is standard
• kami tetap akan berkhemah is also standard
• the whole sentence would sound fine in normal speech and writing

If you wanted a slightly more casual spoken style, some speakers might say:

• Kalau hujan pun malam ini, kami tetap akan berkhemah.

That has a similar meaning, though the exact rhythm and emphasis are a bit different.

Usually, tetap is better here.

• tetap = still / nevertheless / unchanged despite circumstances
• masih = still, in the sense of continuing in time

In this sentence, the idea is despite the rain, the plan does not change, so tetap is the natural choice.

Masih akan berkhemah is not impossible, but it sounds less precise for this context.
A learner should prefer tetap akan berkhemah here.

Yes, fairly strong certainty.

The combination of:

• kalaupun = even if
• tetap = still / nevertheless
• akan = will

shows that the speakers have already decided. It sounds like a firm plan:

• rain is possible
• but the camping will happen anyway

So the sentence carries both future meaning and determination.
