Ketika hujan tiba-tiba turun, kami menepi sebentar di bawah atap warung.

Ketika means when. It introduces the time clause: when the rain suddenly fell / when it suddenly started raining.

In this sentence:

Ketika hujan tiba-tiba turun, kami menepi sebentar di bawah atap warung.

the first part gives the situation, and the second part tells what we did.

A very natural alternative is saat: Saat hujan tiba-tiba turun, kami menepi sebentar...

Both are common, though ketika can sound a little more formal in some contexts.

Yes, hujan means rain, but Indonesian often says hujan turun, literally rain falls or rain comes down.

So:

• hujan = rain
• turun = to go down, descend, fall

Together, hujan turun means it rains / rain falls.

This is a very normal expression in Indonesian. English usually just says it started raining, but Indonesian often describes the rain as falling.

Tiba-tiba means suddenly.

In this sentence, it modifies the event of the rain falling:

hujan tiba-tiba turun = the rain suddenly fell / it suddenly started raining

Its placement is flexible enough in many cases, but this position is very natural. You may also hear:

• Ketika tiba-tiba hujan turun...
• Ketika hujan turun tiba-tiba...

But the original version sounds the most natural and clear.

This is an important Indonesian distinction:

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

So kami menepi means we pulled over / we moved aside, but the listener is not part of that we.

English has only one we, so this difference is something English speakers often need to get used to.

Menepi means something like:

• to move to the side
• to pull over
• to step aside
• to go to the edge

In this sentence, it suggests that we moved out of the rain and sheltered at the side, probably near a roadside stall.

The exact English translation depends on context:

• if on a motorcycle or in a car: pulled over
• if on foot: moved aside or took shelter by the side

It comes from tepi, which means edge or side. The prefix meN- turns it into a verb.

Sebentar means for a moment, briefly, or for a short while.

So:

kami menepi sebentar = we pulled over for a moment / we stopped briefly

It tells you the action was temporary. Without sebentar, the sentence would simply say that they moved aside or pulled over, but not for how long.

It means under the roof of a stall/shop.

Breakdown:

• di bawah = under, underneath
• atap = roof
• warung = a small shop, food stall, roadside stall, or modest kiosk

So the image is that they sheltered under the overhanging roof of a warung while it rained.

Depending on context, warung can be translated as:

• stall
• small shop
• food stall
• roadside shop

Indonesian does not use articles like a, an, and the the way English does.

So atap warung literally looks like roof stall, but it means the roof of a stall or a stall’s roof, depending on context.

This kind of noun relationship is very common in Indonesian:

• atap warung = the stall’s roof / roof of the stall
• pintu rumah = the house door / the door of the house
• nama saya = my name

Context usually makes it clear whether English should use a or the.

Not exactly.

• warung usually refers to a small, simple stall or modest shop, often family-run, and very often connected with food or everyday goods
• toko is a more general word for shop/store

So warung gives a more specific cultural image than toko. In this sentence, warung suggests a roadside place with some kind of roof or awning where people could shelter from rain.

Yes, absolutely. That is probably one of the most natural English translations.

Even though the Indonesian literally says something like when the rain suddenly fell, natural English often prefers:

• when it suddenly started raining
• when it suddenly began to rain

So learners should not expect a word-for-word match. The Indonesian expression is natural in its own way.

Yes, it could be reversed.

Original: Ketika hujan tiba-tiba turun, kami menepi sebentar di bawah atap warung.

Also natural: Kami menepi sebentar di bawah atap warung ketika hujan tiba-tiba turun.

Putting the ketika clause first gives a nice narrative flow: first the situation, then the response. This is very common in storytelling.

Not necessarily.

It more directly means they were under the stall’s roof. That could mean:

• under the awning
• under the overhang
• just outside but protected
• possibly inside, depending on the situation

The phrase itself focuses on the physical shelter, not specifically on being indoors.

It is natural and understandable, and it works well in standard Indonesian.

A few notes:

• ketika is slightly more formal than waktu or pas
• menepi is a good standard verb
• warung is very common everyday vocabulary

In casual speech, someone might say something like:

Pas hujan tiba-tiba turun, kami menepi sebentar di bawah atap warung.

That sounds a bit more conversational, but the original sentence is perfectly normal.
