Kız kardeşim karnabahar sevmiyor, ama ben seviyorum.

Kız kardeş literally means female sibling, and -im means my.

So:

• kız kardeş = sister
• kız kardeşim = my sister

Turkish usually shows possession with a suffix instead of a separate word like my.

A few related forms:

• kız kardeşin = your sister
• kız kardeşi = his/her sister
• kız kardeşimiz = our sister

Because Turkish often expresses possession by adding an ending directly to the noun.

Here the noun is kız kardeş, and the possessive ending is -im:

• kız kardeş + im → kız kardeşim

This is very common in Turkish:

• evim = my house
• annem = my mother
• kitabım = my book

So instead of saying something like my sister, Turkish builds the meaning into the word itself.

No. Kız kardeş just means sister in general.

It does not by itself tell you whether she is older or younger.

If Turkish speakers want to be more specific, they can say things like:

• abla = older sister
• küçük kız kardeş = little/younger sister

But in your sentence, kız kardeşim simply means my sister.

Karnabahar means cauliflower.

In Turkish, there are no words exactly like English a/an or the in most ordinary cases. A bare noun can often mean a general thing or category.

So:

• karnabahar sevmiyor = (she) doesn’t like cauliflower

This sounds natural for talking about likes and dislikes in general, just like English says I like coffee or She doesn’t like broccoli.

If Turkish wanted to make the object more specific, it could mark it differently, but here the general meaning is the normal one.

It breaks down like this:

• sev- = like / love
• -mi- / -mı- / -mu- / -mü- = negative marker
• -yor = present continuous / present tense form
• (third person singular has no extra ending here)

So:

• seviyor = he/she likes / is liking
• sevmiyor = he/she does not like / is not liking

In this sentence, it is best understood as doesn’t like.

The Turkish -yor form is often taught as the present continuous, but in real Turkish it is also very commonly used for general present meaning.

So:

• seviyorum can mean I like
• it can also literally be a present-in-progress form depending on context

In English, I am liking cauliflower sounds unusual, but in Turkish seviyorum is the normal way to say I like it.

Here:

• ben seviyorum = I like it

Good question. The ending -um in seviyorum already tells us the subject is I.

So Turkish could simply say:

• Kız kardeşim karnabahar sevmiyor, ama seviyorum.

That would still be understandable.

But ben is added for emphasis or contrast:

• ama ben seviyorum = but I do like it

So here ben is not required for grammar; it is there to highlight the contrast between my sister and me.

Because Turkish, like English, often leaves out information that is already obvious from context.

The full idea is:

• Kız kardeşim karnabahar sevmiyor, ama ben karnabahar seviyorum.

But repeating karnabahar sounds unnecessary, so Turkish naturally omits it in the second clause:

• ... ama ben seviyorum.
• ... but I like it.

The object is understood from the first clause.

The sentence follows a very typical Turkish pattern:

• Kız kardeşim = subject
• karnabahar = object
• sevmiyor = verb

So the first clause is:

• My sister + cauliflower + doesn’t like

Turkish often uses Subject–Object–Verb order, unlike English, which usually uses Subject–Verb–Object.

The second clause is similar:

• ama ben seviyorum = but I like it

Here the object is omitted, but the verb still comes at the end.

Ama means but.

So:

• ..., ama ben seviyorum. = ..., but I like it.

Yes, it can often be replaced by fakat, which also means but:

• Kız kardeşim karnabahar sevmiyor, fakat ben seviyorum.

Both are correct. Ama is very common and feels natural in everyday speech.

Because Turkish forms the negative by inserting a negative element between the verb stem and the tense marker.

Compare:

• sev-iyor-um = I like
• sev-mi-yor-um = I do not like

And in third person:

• sev-iyor = he/she likes
• sev-mi-yor = he/she does not like

So the negative is not made with a separate word like English not. It is built into the verb itself.

In this context, it expresses a general preference:

• My sister doesn’t like cauliflower, but I do.

Even though the -yor form can sometimes describe something happening right now, with verbs like sevmek (to like/love) it very often expresses a usual attitude or preference.

So learners should understand this sentence as a statement about tastes, not necessarily about one single moment.

Yes, that is a very natural literal translation.

The second clause does not repeat karnabahar, but the meaning is clearly:

• ama ben seviyorum = but I like it

So if you want to make the English clearer, adding it is perfectly normal, even though there is no separate word for it in the Turkish sentence.
