Kakak perempuan saya cerdas, tetapi kadang terlalu ceroboh saat menyimpan kunci.

In Indonesian, possessive words usually come after the noun.

So:

• kakak perempuan saya = my older sister
• literally: older sister female my

This is normal Indonesian word order. It works the same way with many nouns:

• rumah saya = my house
• teman saya = my friend
• buku saya = my book

Kakak means an older sibling. It does not by itself mean specifically brother or sister.

To make the gender clear, Indonesian can add:

• kakak perempuan = older sister
• kakak laki-laki = older brother

So kakak perempuan saya specifically means my older sister.

This is different from English, because Indonesian often distinguishes siblings by age rather than using one single word like sister.

Yes, in many real-life situations, kakak alone is enough if the gender is already understood from context.

For example, if someone is talking about their family and everyone knows they mean a female sibling, they may simply say:

• Kakak saya cerdas.

But kakak perempuan is clearer and more explicit.

Indonesian often leaves out the verb to be when linking a subject to an adjective or noun.

So:

• Kakak perempuan saya cerdas = My older sister is smart
• literally: My older sister smart

This is completely normal.

More examples:

• Dia senang = He/She is happy
• Rumah itu besar = That house is big

You do not need a word like is here.

Both can mean smart or intelligent, but there is a slight difference in feel.

• cerdas often sounds more like intelligent, bright, or clever
• pintar can mean smart, good at something, or skilled

In many everyday sentences, they overlap and either could work.
But cerdas often feels a little more formal or focused on intellectual ability.

So:

• Dia cerdas = She is intelligent
• Dia pintar matematika = She is good at math

Tetapi means but or however.

• Kakak perempuan saya cerdas, tetapi kadang terlalu ceroboh... = My older sister is smart, but sometimes too careless...

Tapi is a shorter, more conversational version of tetapi.

So:

• tetapi = a bit more formal or neutral
• tapi = very common in speech and informal writing

Both are correct.

Yes. Kadang means sometimes, and it is closely related to kadang-kadang, which also means sometimes.

In many cases:

• kadang = sometimes
• kadang-kadang = sometimes

The repeated form can sound a bit more natural or emphatic in some contexts, but both are common.

So this sentence could also be:

• ... tetapi kadang-kadang terlalu ceroboh ...

Not exactly. Terlalu means too in the sense of excessively.

So:

• sangat ceroboh = very careless
• terlalu ceroboh = too careless

That means the carelessness is more than is acceptable or desirable.

Examples:

• terlalu panas = too hot
• terlalu mahal = too expensive

So in this sentence, terlalu ceroboh suggests that her carelessness causes problems.

It means when storing/putting away the keys or when keeping the keys.

Breakdown:

• saat = when, at the time of
• menyimpan = to store, to put away, to keep
• kunci = key or keys

So the phrase describes the situation in which she is careless:
when putting away the keys / when keeping track of the keys.

Menyimpan is the active verb form with the prefix meN-.

Base form:

• simpan = store, keep, put away (dictionary/root form)

Active verb:

• menyimpan = to store, to keep, to put away

This meN- prefix is very common in Indonesian for active verbs.

Other examples:

• baca → membaca = read
• beli → membeli = buy
• simpan → menyimpan = store/keep

This happens because of a common sound change with the meN- prefix.

When the root begins with s, the s usually disappears and meN- becomes meny-.

So:

• simpan → menyimpan
• sapu → menyapu
• sebut → menyebut

This is a regular pattern in Indonesian verb formation.

It can mean either a key or keys, depending on context.

Indonesian nouns usually do not change form for singular vs. plural the way English nouns do.

So:

• kunci = key or keys

If the speaker wants to make plurality very clear, they might say:

• kunci-kunci = keys
• or use context/number words, such as dua kunci = two keys

In this sentence, English would naturally translate it as keys, but the Indonesian word itself does not force that.

Yes, often it could.

• saat = when, at the time
• waktu can also mean when in many contexts

So this would also sound natural:

• ... terlalu ceroboh waktu menyimpan kunci.

However, saat can sound slightly more formal or polished in writing, while waktu is very common in everyday speech.

Yes, very typical.

Structure:

• Kakak perempuan saya = subject
• cerdas = adjective/predicate
• tetapi = conjunction
• kadang terlalu ceroboh = second predicate idea
• saat menyimpan kunci = time phrase

Indonesian often uses a straightforward order like:

Subject + adjective/predicate + conjunction + time phrase

Also, adjectives can function directly as predicates without needing is, which is one of the biggest differences from English.
