Kız kardeşim biraz inatçı, ama sonunda annemi dinliyor.

In Turkish, kız kardeş means sister literally girl sibling.

The ending -im on kardeş means my, so:

• kız kardeş = sister
• kız kardeşim = my sister

This is very common in Turkish: possession is usually shown by adding a suffix to the noun rather than using a separate word like my.

Turkish often puts possession directly on the noun, so kız kardeşim already means my sister.

You can say benim kız kardeşim, but that is more explicit or emphatic:

• kız kardeşim = my sister
• benim kız kardeşim = my sister / my sister

So in this sentence, benim is unnecessary because the -im ending already shows the meaning.

Biraz means a little, somewhat, or rather.

So biraz inatçı means:

• a little stubborn
• somewhat stubborn
• kind of stubborn

It softens the adjective inatçı and makes the statement less absolute than just saying inatçı.

Yes, inatçı is an adjective. It means stubborn.

So:

• Kız kardeşim inatçı. = My sister is stubborn.
• Kız kardeşim biraz inatçı. = My sister is a little stubborn.

Turkish does not need a separate word for is in sentences like this in the present tense.

In Turkish, the verb to be is often omitted in simple present-tense descriptive sentences.

So:

• Kız kardeşim biraz inatçı. literally looks like My sister a little stubborn but naturally means My sister is a little stubborn.

This is completely normal in Turkish. English requires is, but Turkish usually does not in this type of sentence.

Ama means but.

It connects the two ideas:

• Kız kardeşim biraz inatçı = My sister is a little stubborn
• ama sonunda annemi dinliyor = but in the end she listens to my mother

So ama works just like but in English.

Sonunda means in the end, eventually, or finally.

In this sentence, it shows that even though the sister is stubborn, she eventually listens.

It comes from son = end, with an ending that gives the sense of at the end / in the end.

So:

• sonunda = in the end / eventually

This is because the verb dinlemek normally takes a direct object, and that object is often marked with the accusative ending.

Here:

• annem = my mother
• annemi = my mother, as the object of the verb

Since the sentence says she is listening to the mother, Turkish uses:

• annemi dinliyor = she is listening to my mother

So the -i marks annemi as the definite object.

This is an important difference between English and Turkish.

In English, we say:

• listen to my mother

But in Turkish, dinlemek works more like to listen/hear/pay attention to someone, and it takes a direct object:

• annemi dinliyor

So you should think of dinlemek as a verb that directly takes the person or thing being listened to. You do not use a separate word corresponding to English to here.

Dinliyor is in the present continuous form, built with -iyor.

From the verb dinlemek = to listen:

• stem: dinle-
• present continuous: dinliyor = is listening / listens

In Turkish, this form is often used not only for something happening right now, but also for a regular or typical action in everyday speech.

So here dinliyor can mean:

• she is listening
• she does listen
• she ends up listening

depending on context.

Both are possible in Turkish, but they give slightly different feels.

• dinliyor often sounds more immediate, vivid, or conversational
• dinler is more like a general habitual statement

In this sentence, sonunda annemi dinliyor sounds very natural for but in the end she listens to my mother. It suggests what usually happens in the end, in a lively spoken way.

So Turkish often uses the present continuous where English might use a simple present.

The subject is still kız kardeşim = my sister.

Turkish often leaves out subject pronouns when the subject is already clear from context. So after saying Kız kardeşim..., the second part naturally continues with the same subject:

• ama sonunda annemi dinliyor = but in the end she listens to my mother

There is no need to say o for she unless you want emphasis.

Yes, Turkish word order is flexible, but the given order is natural and clear.

The sentence is:

• Kız kardeşim biraz inatçı, ama sonunda annemi dinliyor.

A very literal breakdown is:

• Kız kardeşim = my sister
• biraz inatçı = a little stubborn
• ama = but
• sonunda = in the end
• annemi = my mother
• dinliyor = is listening / listens

Turkish often puts the verb near the end, as here. You could move some parts for emphasis, but this version is a normal neutral sentence.

Yes, very often birini dinlemek means not only to listen to someone, but also to heed them, to pay attention to them, or to obey what they say.

So in this sentence, depending on context, annemi dinliyor can suggest:

• she listens to my mother
• she pays attention to my mother
• she obeys my mother

That is probably the intended sense here, especially because it follows she is a little stubborn, but in the end...
