Jari saya sakit karena terlalu lama mengetik.

It can mean either finger or fingers.

In Indonesian, nouns often do not have to be marked for plural. Context usually tells you whether one or more is meant. So:

• Jari saya sakit can mean my finger hurts or my fingers hurt
• If you really want to emphasize plural, you might say jari-jari saya sakit

A small warning: jari-jari can also mean radius in math, so Indonesian often leaves jari un-doubled unless the context clearly needs plural emphasis.

Because possession in Indonesian is usually expressed as:

noun + possessor

So:

• jari saya = my finger(s)
• rumah saya = my house
• teman saya = my friend

This is different from English, where the possessor usually comes first: my finger.

In casual Indonesian, you may also hear the suffix form:

• jariku = my finger(s)

Indonesian often leaves out the verb to be when describing something.

So:

• Jari saya sakit literally looks like my finger(s) sore/painful
• Natural English: My finger hurts / My fingers hurt

This is very normal in Indonesian. You do not need a separate word like is or are here.

Here, sakit means something like hurt, sore, or painful.

Its meaning depends on what it describes:

• Saya sakit = I am sick/ill
• Jari saya sakit = my finger hurts / my fingers hurt
• Kepala saya sakit = my head hurts

So with a body part, sakit usually means in pain rather than ill.

Karena means because.

It introduces the reason:

• Jari saya sakit = the result
• karena terlalu lama mengetik = the reason

So the structure is:

[main statement] + karena + [reason]

You can also reverse it:

• Karena terlalu lama mengetik, jari saya sakit.

That also means Because I typed for too long, my fingers hurt.

It means both, depending on how English naturally expresses it.

• terlalu = too, overly, excessively
• lama = long (in time)

So terlalu lama mengetik literally means typing too long or typing for too long.

In natural English, for too long is usually the best translation in this sentence.

The base word is ketik, which relates to typing.

mengetik is the active verb form, meaning to type or typing.

This comes from the meN- prefix, which often makes active verbs. When meN- is added to a root starting with k, the k usually disappears:

• ketik → mengetik

So:

• mengetik = to type
• sedang mengetik = is typing
• saya mengetik = I type / I am typing

Bare ketik can appear in some situations, but mengetik is the normal verb form here.

It is simply omitted because it is not important here.

Indonesian often leaves out objects when they are obvious or not needed. So:

• mengetik = to type / typing
• no object is necessary if the point is just the action itself

If you wanted, you could add one:

• mengetik laporan = typing a report
• mengetik email = typing an email

But in this sentence, the speaker only wants to say that the fingers hurt because of typing, not because of typing some specific thing.

Indonesian does not mark tense the way English does.

This sentence does not explicitly say typed, have been typing, or am typing. The time is understood from context.

So Jari saya sakit karena terlalu lama mengetik can naturally be understood as:

• My fingers hurt because I typed for too long
• My fingers hurt because I’ve been typing too long
• My fingers hurt from typing too long

If needed, Indonesian can add time words such as:

• tadi = earlier
• sejak tadi = since earlier
• sudah = already
• sedang = currently

But none are required here.

You can say it differently depending on formality.

• Jari saya sakit karena terlalu lama mengetik. → neutral/polite
• Jari aku sakit karena terlalu lama mengetik. → informal
• Jariku sakit karena terlalu lama mengetik. → very natural casual form

So saya is not the only option, but it is a safe and standard one for learners.

Yes, but it sounds a bit more literary or expressive.

• jari = the normal everyday word for finger(s)
• jemari = a more poetic or elegant word for fingers

So in ordinary conversation, jari is the most natural choice.

Yes.

You can say:

• Jari saya sakit karena terlalu lama mengetik.
• Karena terlalu lama mengetik, jari saya sakit.

Both are correct.

The second version emphasizes the cause a little more, while the first is the more straightforward statement-result order.
