Questions & Answers about Jangan-jangan kostumnya disimpan di rumah.

Why does jangan-jangan not mean don't don't?

Because jangan-jangan is a fixed idiomatic expression, not just jangan repeated literally.

• jangan by itself = don't
• jangan-jangan = maybe, what if, I have a suspicion that..., often with a worried or uneasy feeling

So in this sentence, it signals speculation, not a command.

What feeling does jangan-jangan add to the sentence?

It usually adds a sense of suspicion, concern, or nervous guessing.

It is often used when the speaker is thinking something like:

• Could it be that...
• What if...
• Don't tell me...

So the sentence does not sound like a neutral factual statement. It sounds more like the speaker is guessing and is somewhat uneasy or doubtful.

Why is jangan-jangan written with a hyphen?

Because it is a reduplicated form. In Indonesian spelling, full reduplication is commonly written with a hyphen.

Examples:

• anak-anak = children
• pelan-pelan = slowly / take it easy
• jangan-jangan = perhaps / what if

In this case, the reduplication creates an idiomatic expression.
