Tolong tutup jendela itu dengan rapat supaya asap tidak masuk.

Tolong is commonly used to make a request polite. In this sentence, it works like please in English:

• Tolong tutup jendela itu... = Please close that window...

On its own, tolong can also mean help, depending on context. But before a verb like tutup, it usually softens the command and turns it into a polite request.

Because this is a request or command.

In Malay, the base verb is often used in imperatives:

• Tutup jendela itu. = Close that window.
• Tolong tutup jendela itu. = Please close that window.

The form menutup is more typical in statements:

• Dia menutup jendela itu. = He/She is closing that window.

So tutup here is normal because the speaker is telling someone to do something.

Jendela itu literally means window that.

Malay usually puts demonstratives after the noun:

• jendela ini = this window
• jendela itu = that window

This is different from English, where this and that come before the noun.

So:

• jendela itu = that window

No. Another very common word is tingkap.

Both can mean window, but usage can vary by region and style:

• jendela is widely understood
• tingkap is also very common, especially in Malaysia

So you may also hear:

• Tolong tutup tingkap itu...

Both are natural.

Dengan rapat means tightly, firmly, or all the way shut.

Word by word:

• dengan = with
• rapat = close, tight, snug

In this sentence, it tells you how to close the window:

• tutup ... dengan rapat = close ... tightly

It implies not leaving any gap open.

In Malay, adverbial expressions are often formed with dengan + adjective.

So:

• rapat = close/tight
• dengan rapat = tightly

This is a very natural way to describe how an action is done. Even though English might just use an adverb, Malay often uses this structure.

Supaya means so that or in order that.

It introduces the purpose of the action:

• Tolong tutup jendela itu dengan rapat supaya asap tidak masuk.
• Please close that window tightly so that smoke does not come in.

A common alternative is agar, which means nearly the same thing:

• ... agar asap tidak masuk.

Both are correct and natural.

Because tidak is used to negate verbs and adjectives, while bukan is usually used to negate nouns or noun phrases.

Here, masuk is a verb:

• asap tidak masuk = the smoke does not enter / does not come in

Compare:

• Dia tidak datang. = He/She is not coming.
• Itu bukan jendela. = That is not a window.

So tidak is the correct negator in this sentence.

Masuk means enter, go in, or come in.

In this sentence:

• asap tidak masuk = the smoke does not come in / enter

Malay often uses masuk where English might choose different phrasings depending on context, such as come in, get in, or enter.

Malay often does not need an extra word like into when the meaning is already clear from context.

So:

• asap tidak masuk literally = smoke not enter
• natural English = the smoke doesn’t come in

If needed, Malay can add more detail, such as where something enters, but it is not necessary here because the situation is obvious: the smoke would come into the room through the window.

It is grammatically a command, but tolong makes it sound like a polite request.

Without tolong:

• Tutup jendela itu. = stronger, more direct

With tolong:

• Tolong tutup jendela itu. = softer, more polite

So it is best understood as Please close that window tightly...

That is much less natural for a direct request.

For commands and requests, Malay usually prefers the base verb:

• Tolong tutup jendela itu. ✅

Using menutup after tolong can sometimes appear in formal or unusual structures, but for everyday speech, tolong + base verb is the normal pattern.

Yes, but the meaning becomes less specific.

• Tolong tutup jendela itu... = Please close that window...
• Tolong tutup jendela... = Please close the window / a window...

Using itu points to a specific window already known in the situation.

Some parts can move, but the original order is the most natural.

Standard order:

• Tolong tutup jendela itu dengan rapat supaya asap tidak masuk.

You might also hear small variations, but not all changes sound equally natural. For example, moving itu before jendela would be wrong:

• itu jendela = possible in some contexts as that is a window
• itu jendela does not mean that window

So for that window, keep:

• jendela itu

Both are possible, but they mean slightly different things.

• asap tidak masuk = the smoke does not come in
• asap tidak boleh masuk = the smoke must not / cannot come in

The original sentence focuses on the result you want: close the window tightly so that the smoke doesn’t come in. It sounds natural and straightforward.

If you use tidak boleh, the tone shifts more toward prohibition or impossibility.

Yes, but the tone changes slightly.

• Tolong = please, often used in everyday requests
• Sila = also please, but often more formal, polite, or instructional

So:

• Tolong tutup jendela itu... = natural everyday request
• Sila tutup jendela itu... = more formal or official-sounding

Both are correct, but tolong fits casual spoken Malay very well.
