Apabila adik lelaki saya resah pada waktu malam, ibu menepuk belakangnya perlahan sampai dia menguap.

Apabila means when or whenever.

In this sentence, it introduces the situation that triggers the main action:

• Apabila adik lelaki saya resah... = When/Whenever my younger brother is restless...

A few useful comparisons:

• apabila — a bit more formal or written
• bila — very common in everyday speech
• ketika — often translated as when, sometimes a little more literary or formal

So this sentence could also be said more casually with bila.

Malay can put the time/condition clause first, just like English can:

• When my younger brother is restless at night, mother...

This is very natural in Malay. It sets the scene before the main action.

You could also change the order:

• Ibu menepuk belakangnya perlahan apabila adik lelaki saya resah pada waktu malam.

That is also grammatical, but starting with apabila... gives a smoother when X happens, Y happens structure.

Adik lelaki saya means my younger brother.

Breakdown:

• adik = younger sibling
• lelaki = male
• saya = my / I

So literally it is something like:

• younger sibling male my

Natural English: my younger brother

A very important point for English speakers: adik by itself does not mean specifically brother. It means younger sibling, so lelaki is added to show that the sibling is male.

Because Malay noun phrases usually put the main noun first, and then the words that describe or specify it come after.

So:

• adik lelaki = younger sibling + male
• adik lelaki saya = my younger brother

This is normal Malay word order.

Compare with English:

• English: my younger brother
• Malay: adik lelaki saya

The same pattern happens in many Malay phrases:

• rumah besar = big house
• kereta saya = my car

So it is very normal that lelaki and saya follow adik.

In Malay, family terms are often used without a possessive when the relationship is already obvious from context.

So:

• ibu menepuk... = mother pats...
• naturally understood as my mother here

Because the sentence already includes saya in adik lelaki saya, the speaker’s perspective is clear. Malay often avoids repeating possessives when they are obvious.

If you said ibu saya, that would also be correct, but it may sound a bit more explicit than necessary in this sentence.

Resah means something like:

• restless
• uneasy
• fussy
• agitated

In this sentence, it suggests that the younger brother is unsettled at night, maybe unable to relax or sleep comfortably.

It is a useful word because it can describe both:

• emotional uneasiness
• physical restlessness

So here resah is broader than just worried.

Pada waktu malam literally means at the time of night, but the natural English meaning is simply at night.

Breakdown:

• pada = at/on/in (depending on context)
• waktu = time
• malam = night

So:

• pada waktu malam = at night / during the night

About pada:

• It is common with time expressions.
• But in everyday Malay, people often use shorter versions too, such as:
  • waktu malam
  • malam

So this sentence could be shortened in casual speech, but pada waktu malam sounds completely natural and slightly fuller.

Menepuk is the active verb form built from the root tepuk.

Breakdown:

• tepuk = clap, pat, tap
• meN- = a common verb-forming prefix
• tepuk → menepuk

The initial t drops after this prefix, which is a normal sound change in Malay morphology.

So:

• tepuk = the root idea
• menepuk = to pat / to tap / to clap

In this sentence, menepuk belakangnya means patting his back.

Belakangnya means his back or her back, depending on context.

Breakdown:

• belakang = back
• -nya = his / her / its

So:

• belakangnya = his/her back

Here, -nya refers to adik lelaki saya, so the meaning is his back.

This -nya ending is very common in Malay. It can show possession:

• bukunya = his/her book
• rumahnya = his/her house

So belakangnya is a very normal way to say his back.

Because in Malay, words that work like adverbs often come after the verb.

So:

• menepuk belakangnya perlahan = pat his back gently / slowly

That is normal Malay word order.

Also, perlahan can mean:

• slow
• slowly
• gentle/gently in the right context

Here it describes how the patting is done, so gently is the best natural meaning.

You may also see:

• dengan perlahan = gently / slowly
• perlahan-lahan = slowly, gently

All are possible, but perlahan on its own is perfectly natural here.

Here sampai means until or to the point that.

So:

• ibu menepuk belakangnya perlahan sampai dia menguap
• mother gently pats his back until he yawns

It shows the action continues up to a result.

Important: sampai can have different meanings in Malay, including arrive or reach, but in this sentence it clearly means until.

So the structure is:

• action continues
• result happens

That is why until he yawns is a good translation.

Because Malay dia does not mark gender.

It can mean:

• he
• she

Malay relies on context instead.

In this sentence, the most logical referent is adik lelaki saya, so dia is understood as he.

Even though ibu is also mentioned, the meaning is clear because:

• the action of patting is done by ibu
• the yawning is naturally done by the restless younger brother

So there is no real confusion in context.

Malay verbs usually do not change form for tense the way English verbs do.

So:

• resah
• menepuk
• menguap

do not by themselves tell you past, present, or future.

Malay usually shows time through:

• context
• time words
• aspect markers such as sedang, sudah, akan

In this sentence, because of apabila and the general situation being described, it most naturally sounds habitual or general:

• When/Whenever my younger brother is restless at night, mother gently pats his back until he yawns.

But in the right story context, it could also be understood as a past event. Context decides.

Mostly it gives a sense of result here, not purpose.

It means the mother keeps patting his back until the result is that he yawns.

English sometimes makes result and purpose sound similar, but in Malay this structure usually points to what happens as the outcome of the action.

So the idea is closer to:

• She pats his back gently, and eventually he yawns

rather than:

• She pats his back in order to make him yawn

The second idea is not impossible as an implication, but the grammar here mainly presents the result.

It is mostly neutral, with a slightly polished feel because of apabila and pada waktu malam.

Why it feels a bit polished:

• apabila is a little more formal than bila
• pada waktu malam is fuller than just malam

But the sentence is still very natural and not stiff.

A more casual spoken version might be:

• Bila adik lelaki saya resah waktu malam, ibu tepuk belakang dia perlahan sampai dia menguap.

That version is more conversational, while the original sounds a little more careful and standard.
