Jahitan itu rosak.

Jahitan comes from the root jahit, which means to sew or to stitch.

With the ending -an, jahitan usually means stitching, seam, stitches, or the sewn part, depending on context. In this sentence, it most naturally refers to the stitching / the seam.

So it is not the action to sew here, but the result or thing produced by sewing.

Itu usually means that.

In Jahitan itu rosak, it points to a specific seam or stitching that both speaker and listener can identify: that seam / that stitching.

Malay often puts itu after the noun, not before it. So:

• jahitan itu = that seam / the stitching
• literally: seam that

In natural English, this is often translated as either that seam or simply the seam, depending on context.

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• baju itu = that shirt
• rumah itu = that house
• jahitan itu = that seam / that stitching

This is a normal Malay word order pattern. English puts that before the noun, but Malay usually puts itu after it.

Rosak means damaged, spoiled, broken, ruined, or faulty, depending on context.

In this sentence, rosak is describing the condition of jahitan itu. So it means the seam or stitching is damaged, bad, or coming apart.

Malay does not need a separate word like is in this kind of sentence. So:

• Jahitan itu rosak
  = The seam is damaged / That stitching is bad

There is no separate word for is here, because Malay often leaves it out in simple descriptive sentences.

So a pattern like:

• X rosak = X is damaged
• X cantik = X is beautiful
• X besar = X is big

is completely normal.

That means:

• Jahitan itu rosak literally looks like That seam damaged
• but natural English is That seam is damaged

In beginner-level learning, it is most helpful to think of rosak here as an adjective-like word meaning damaged / broken.

However, Malay words can be flexible, and rosak can also behave in ways that feel verbal in English, such as to become damaged or to break down, depending on the sentence.

In Jahitan itu rosak, it is best understood as a description of the seam’s condition: The seam is damaged.

Yes, you can.

A simple pronunciation guide is:

• jahitan → ja-hi-tan
