Anting itu cocok dengan gaun biru kakak perempuan saya.

A simple breakdown is:

• Anting itu = that earring / those earrings
• cocok dengan = matches / goes well with
• gaun biru kakak perempuan saya = my older sister’s blue dress

So the overall structure is:

• subject: Anting itu
• predicate: cocok dengan gaun biru kakak perempuan saya

Indonesian often builds meaning by stacking nouns and modifiers, so it helps to read the last part as one chunk: the blue dress of my older sister.

In Indonesian, demonstratives like ini and itu usually come after the noun.

So:

• anting itu = that earring / those earrings
• gaun itu = that dress
• buku ini = this book

This is different from English, where this/that comes before the noun.

Cocok means something like:

• suitable
• well-matched
• goes well
• fits well (depending on context)

With clothes, accessories, and colors, cocok dengan often means matches or goes well with.

So:

• Anting itu cocok dengan gaun biru... = That earring goes well with the blue dress...

The word dengan here means with and connects the thing being matched to what it matches.

You can say cocok by itself, but adding dengan makes it clear what it matches.

Compare:

• Anting itu cocok. = That earring is suitable / looks good.
• Anting itu cocok dengan gaun biru. = That earring matches the blue dress.

So dengan introduces the thing it goes with.

Yes.

• cocok dengan = matches / is compatible with
• cocok untuk = is suitable for

Examples:

• Baju ini cocok dengan sepatu itu. = This shirt matches those shoes.
• Baju ini cocok untuk pesta. = This shirt is suitable for a party.

In your sentence, the idea is matching, so dengan is the natural choice.

Because in Indonesian, adjectives usually come after the noun.

So:

• gaun biru = blue dress
• rumah besar = big house
• mobil merah = red car

This is the normal Indonesian word order for noun + adjective.

Kakak perempuan saya means my older sister.

Breaking it down:

• kakak = older sibling
• perempuan = female
• saya = my / I depending on position; here it means my

So literally it is something like my female older sibling.

A few useful comparisons:

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

It belongs to the whole phrase before it in the sense of possession:

• gaun biru kakak perempuan saya = my older sister’s blue dress

Indonesian usually puts the possessor after the thing possessed.

So compare:

• buku saya = my book
• rumah teman saya = my friend’s house
• gaun biru kakak perempuan saya = my older sister’s blue dress

English uses my older sister’s blue dress. Indonesian literally orders it more like blue dress older sister my.

Usually no. It is naturally understood as my older sister’s blue dress.

If you want to make the possession extra explicit, you could say:

• gaun biru milik kakak perempuan saya

Here milik means belonging to.

But in everyday Indonesian, the original version is already clear and natural.

Because Indonesian often does not use a present-tense copula like English is/are.

So:

• Anting itu cocok... literally looks like That earring suitable/matching...
• but in natural English it becomes That earring is suitable / matches...

This is very normal in Indonesian. You usually do not need adalah here.

By itself, anting does not clearly mark number the way English does.

Depending on context, it could refer to:

• that earring
• those earrings
• sometimes a pair, if the situation makes that obvious

If you want to be more specific, Indonesian can do that in other ways, for example:

• sebuah anting = one earring
• sepasang anting = a pair of earrings

So the exact number often comes from context.

Good question. Anting-anting is the full, very common dictionary form for earring(s), but in everyday usage people often shorten it to anting.

So in practice:

• anting-anting = standard/full form
• anting = common shortened form

The sentence sounds natural with anting.

Yes. In everyday speech, many speakers say:

• Anting itu cocok sama gaun biru kakak perempuan saya.

Here sama works like with in a more informal way.

Difference in tone:

• dengan = more standard/neutral
• sama = more conversational

Both are common, but the version with dengan is a good standard form for learners.
