Pergelangan tangan saya masih luka, jadi saya tidak bisa bermain bola.

Yes—pergelangan tangan is a multi-word expression.

• pergelangan = the joint area / the part that bends
• tangan = hand / arm

So pergelangan tangan literally refers to the joint of the hand/arm, which is the wrist.

A useful comparison:

• pergelangan tangan = wrist
• pergelangan kaki = ankle

This is very common in Indonesian: body parts are often expressed with descriptive combinations rather than a single word.

Because Indonesian usually does not need a verb like to be in simple sentences.

So:

• Pergelangan tangan saya masih luka literally looks like My wrist still injured/wounded
• Natural English: My wrist is still injured

This is normal in Indonesian:

• Saya sakit = I am sick
• Dia marah = He/She is angry
• Rumahnya besar = His/Her house is big

In many cases, Indonesian simply puts the subject next to the description, without is/am/are.

Masih means still.

So:

• Pergelangan tangan saya luka = My wrist is injured / wounded
• Pergelangan tangan saya masih luka = My wrist is still injured

It shows that the condition continues from before until now.

Common pattern:

• masih + adjective/state/verb

Examples:

• Saya masih capek = I’m still tired
• Dia masih tidur = He/She is still sleeping
• Mereka masih di rumah = They are still at home

Luka can behave a bit flexibly in Indonesian.

In this sentence, luka means something like:

• injured
• wounded
• hurt

So here it works like a state/description.

Depending on context, luka can also refer to:

• a wound as a noun
• injured/wounded as a descriptive word

Examples:

• Saya punya luka di tangan = I have a wound on my hand
• Tangannya luka = His/Her hand is injured

For a sports injury, Indonesians might also say:

• cedera = injured/injury
• terluka = injured/wounded

So your sentence is understandable and natural, though in some contexts cedera might sound a little more specific.

Yes, Indonesian often repeats the subject in a new clause, and that is what happens here:

• Pergelangan tangan saya masih luka, jadi saya tidak bisa bermain bola.

The second saya makes the sentence clear and complete:

• so I cannot play ball

Could you omit it? Sometimes in conversation, yes:

• Pergelangan tangan saya masih luka, jadi tidak bisa bermain bola.

But that sounds more informal and slightly less explicit. Repeating saya is very normal and often preferred, especially for learners.

Good question. Jadi has more than one use.

It can mean:

1. become
2. so / therefore / as a result

In your sentence, it means so / therefore:

• Pergelangan tangan saya masih luka, jadi saya tidak bisa bermain bola.
• My wrist is still injured, so I can’t play ball.

Examples of the two meanings:

• Dia jadi dokter. = He/She became a doctor.
• Hujan, jadi kami pulang. = It’s raining, so we went home.

So here, jadi is a connector showing cause and result.

Because in Indonesian, tidak normally comes before the verb or adjective it negates.

Here:

• bisa = can / be able to
• tidak bisa = cannot / be unable to

So:

• saya bisa bermain bola = I can play ball
• saya tidak bisa bermain bola = I cannot play ball

Bisa tidak is different. It usually appears in questions or contrasts, such as:

• Bisa tidak? = Can you or not?
• Saya bisa, dia tidak. = I can, he can’t.

So for a plain negative statement, tidak bisa is the normal order.

This is a very useful distinction.

• tidak bisa = cannot / am not able to
• belum bisa = cannot yet / am not able to yet

In your sentence:

• saya tidak bisa bermain bola = I can’t play ball

If you said:

• saya belum bisa bermain bola it would suggest:
• I can’t play ball yet
• maybe because recovery is still in progress, but later I probably will be able to

So:

• tidak bisa = plain inability
• belum bisa = not yet able, with a sense of possible future change

Both are possible, but they differ in formality and style.

• bermain bola = more standard / more formal
• main bola = more casual, conversational

Here:

• bermain comes from the root main
• the prefix ber- often forms an intransitive verb, here meaning to play

So:

• bermain bola = to play ball / to play football/soccer
• main bola = same basic meaning, but more informal

As a learner, bermain bola is a very safe and correct choice.

It depends on context.

Literally, bola means ball. But in everyday Indonesian, main bola or bermain bola often strongly suggests playing soccer/football, because that is such a common sport.

So this sentence may be understood as:

• I can’t play ball or more naturally in many contexts:
• I can’t play soccer

If you want to be specific, you can say:

• bermain sepak bola = play soccer/football
• bermain basket = play basketball
• bermain voli = play volleyball

So bola alone is common, but the exact sport comes from context.

Yes, Pergelangan tangan saya is the normal order.

In Indonesian, possession usually works like this:

• noun + possessor

So:

• pergelangan tangan saya = my wrist
• rumah saya = my house
• teman saya = my friend

This is different from English, where the possessor often comes first:

• my wrist
• my house

So Indonesian prefers:

• wrist my
• house my

That is one of the basic word-order differences learners need to get used to.

Yes, but the structure changes.

Your original sentence:

• Pergelangan tangan saya masih luka, jadi saya tidak bisa bermain bola.
• My wrist is still injured, so I can’t play ball.

With karena:

• Saya tidak bisa bermain bola karena pergelangan tangan saya masih luka.
• I can’t play ball because my wrist is still injured.

Difference:

• jadi introduces the result: so
• karena introduces the reason: because

Both are natural; they just organize the information differently.

Your sentence is understandable and natural enough, but there are other common ways to say it depending on nuance.

Possible alternatives:

• Pergelangan tangan saya masih sakit. = My wrist still hurts / is still sore.
• Pergelangan tangan saya masih cedera. = My wrist is still injured.
• Pergelangan tangan saya masih terluka. = My wrist is still hurt/injured.

Rough differences:

• sakit focuses on pain
• luka suggests being wounded/hurt
• cedera is often good for injuries, especially sports injuries
• terluka sounds a bit more explicitly like injured/wounded

So your sentence works, but in a sports context, masih cedera may sound especially natural.
