Dizim düzelince tekrar parkta koşacağım.

Here, dizim means my knee.

It breaks down like this:

• diz = knee
• -im = my

So Turkish often expresses possession by adding a suffix directly to the noun instead of using a separate word like my.

A small note: diz can also mean things like row or sequence in other contexts, but in this sentence it clearly means knee.

Düzelince means when it gets better, once it gets better, or after it gets better depending on context.

It comes from:

• düzelmek = to get better, improve, be fixed, straighten out
• -ince = when / once / after

So:

• düzelince = when it improves / once it gets better

In this sentence, it refers to the knee getting better.

Because Turkish often uses a suffix instead of a separate word.

In English, you say:

• when my knee gets better

In Turkish, that idea is built into the verb:

• dizim düzelince

The suffix -ince does the job of when / once / after.

This is very common in Turkish. Instead of using an extra word, Turkish often attaches meaning directly to the verb.

Yes, düzelmek is natural here, especially in everyday speech.

With injuries or physical problems, düzelmek can mean:

• to get better
• to improve
• to recover
• to return to normal

So dizim düzelince sounds like when my knee is better again.

You could also say:

• Dizim iyileşince tekrar parkta koşacağım.

That would also be correct and natural. İyileşmek is more specifically to heal / recover, while düzelmek is a bit broader and more conversational.

Tekrar means again.

So it tells you that the speaker plans to return to doing something they did before: running in the park.

Its position is fairly flexible in Turkish, although some placements sound more natural than others. In this sentence:

• Dizim düzelince tekrar parkta koşacağım.

the meaning is basically When my knee gets better, I’ll run in the park again.

You could also hear:

• Dizim düzelince parkta tekrar koşacağım.

That is also natural. The difference is mostly about emphasis, not core meaning.

Because of a Turkish sound rule.

The locative suffix is:

• -da / -de
• but after certain voiceless consonants, it becomes -ta / -te

Since park ends in k, which is voiceless, the suffix changes:

• park + da → parkta

So:

• parkta = in the park

This same pattern happens in many words:

• evde = in the house
• okulda = at school
• kitapta = in the book
• ağaçta = on the tree

Koşacağım means I will run.

It comes from:

• koşmak = to run
• future suffix -acak / -ecek
• first person singular ending -ım / -im / -um / -üm

So the structure is:

• koş-acak-ım

But in actual spelling and pronunciation, it becomes:

• koşacağım

That gives you:

• koşacağım = I will run

So the main clause of the sentence is:

• tekrar parkta koşacağım = I will run in the park again

This is a very common question.

In modern Turkish, ğ usually does not sound like a strong English g. In koşacağım, it mainly softens the flow between vowels.

So koşacağım is pronounced roughly like:

• ko-sha-ja-um
• or more smoothly, ko-sha-jım depending on speed

The ğ often lengthens the vowel before it or creates a smooth transition rather than making a hard consonant sound.

So don’t pronounce it like:

• ko-sha-gah-jum

That would sound unnatural.

The sentence has two parts:

1. Dizim düzelince
   = when my knee gets better

2. tekrar parkta koşacağım
   = I will run in the park again

So the whole structure is:

• [time clause] + [main clause]

This is very common in Turkish. The background condition or time phrase often comes first, and the main verb of the sentence comes near the end.

Literally, the order is close to:

• My knee gets-better-when, again in-the-park I-will-run.

That sounds strange in English, but it is normal Turkish structure.

Yes. The subject is clearly dizim.

Turkish does not need to repeat pronouns the way English often does. Since dizim is already there, Turkish does not need to say something like it.

So:

• Dizim düzelince
  already fully means
• when my knee gets better

There is no missing word. The subject is understood from the noun already in the sentence.
