Zip itu tidak rosak sejak tukang jahit menjahitnya.

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

So:

• zip itu = that zip / the zip
• buku ini = this book

This is normal Malay word order. English says that zip, but Malay says zip itu.

Rosak means broken, damaged, spoiled, not functioning properly.

So tidak rosak means not broken / not damaged.

Malay often does not use a verb like is/are in simple statements like this. So:

• Zip itu tidak rosak literally = That zip not broken
• natural English = That zip is not broken

This is very common in Malay. Adjectives can act like predicates without needing a separate to be verb.

Malay has two common negators:

• tidak: used with verbs and adjectives
• bukan: used mainly with nouns and for identification/equation

Since rosak is functioning like an adjective/state (broken, damaged), the correct negation is:

• tidak rosak = not broken

You would not normally say bukan rosak here.

A quick comparison:

• Dia tidak sakit = He/She is not sick
• Dia bukan doktor = He/She is not a doctor

Sejak means since, starting from a point in time or from an event and continuing afterward.

So in this sentence:

• sejak tukang jahit menjahitnya = since the tailor sewed it

This suggests a situation that began after that sewing event and has continued up to the relevant time, usually the present in context.

So the sentence implies something like:

• the zip was sewn by the tailor
• from that time onward, it has not been broken

Yes. The root jahit is related to sewing.

• jahit = sew / sewing
• tukang jahit = tailor, seamster/seamstress, sewing worker

Here, tukang often means a person skilled in a certain type of work or trade. So:

• tukang jahit = literally something like sewing worker / sewing specialist

Then the sentence continues with:

• menjahitnya = sewed it

So you see the same root twice:

• tukang jahit = tailor
• menjahit = to sew

That repetition is completely normal in Malay.

Menjahitnya can be broken down like this:

• meN- = a verb-forming prefix
• jahit = sew
• -nya = it / him / her depending on context

So:

• menjahit = to sew / sewed
• menjahitnya = to sew it / sewed it

In this sentence, -nya refers to zip itu, so it means sewed it.

Malay often attaches object pronouns directly to the verb like this.

Because -nya is a very common attached pronoun in Malay, and here it works naturally as the object it.

So:

• menjahitnya = sewed it

Using dia would usually mean he/she, and it would not fit naturally as the object here in standard usage.

In this sentence, -nya refers back to zip itu. Even though -nya can also mean him/her, the context makes it clear that it means it.

Usually, yes.

Because of sejak (since), the sentence normally implies continuity from the sewing event up to now or up to the current reference point.

So the idea is:

• the tailor sewed the zip
• from that time until now, it has not been broken

That ongoing meaning comes from sejak plus the context, not from a special tense ending on the verb.

Malay verbs usually do not change form for tense the way English verbs do.

So menjahit can mean:

• sews
• is sewing
• sewed
• has sewn

The time is understood from context or from time expressions like sejak.

In this sentence, sejak makes it clear that the sewing happened earlier, so English translates it with a past form: since the tailor sewed it.

Yes. Rosak is a broad word.

Depending on context, it can mean:

• broken
• damaged
• spoiled
• defective
• not working properly

For a zip, tidak rosak most naturally means something like:

• not broken
• not damaged
• still functioning properly

So the exact English wording may vary a little depending on the situation.

Yes, it is commonly used in Malay, especially in everyday speech, as a borrowing referring to a zipper or zip.

In context:

• zip itu = that zip / that zipper

Malay often uses loanwords alongside native or more formal alternatives, and zip is very natural in ordinary usage.
