Kız kardeşim kaşarlı omlet seviyor, ben ise sade omlet tercih ediyorum.

Kız kardeşim means my sister.

It is made of:

• kız = girl / female
• kardeş = sibling / brother / sister
• -im = my

So:

• erkek kardeş = brother
• kız kardeş = sister
• kardeşim by itself can mean my sibling, or in everyday use sometimes my brother/sister depending on context.

Turkish often makes these family terms more specific by adding kız or erkek.

The -im is a possessive suffix meaning my.

So:

• kardeş = sibling
• kardeşim = my sibling / my sister

Turkish usually shows possession with a suffix attached to the noun, instead of using a separate word like my.

A few examples:

• annem = my mother
• babam = my father
• arkadaşım = my friend

So kız kardeşim literally works like sister-my, but in natural English that becomes my sister.

Kaşarlı means with kaşar cheese or cheesy / containing kaşar cheese.

It comes from:

• kaşar = a type of cheese very common in Turkey
• -lı / -li / -lu / -lü = a suffix meaning with / containing

So:

• kaşarlı omlet = cheese omelet, more specifically an omelet with kaşar cheese

This suffix is very useful in Turkish:

• şekerli çay = tea with sugar
• sütlü kahve = coffee with milk
• tuzlu kraker = salty cracker / cracker with salt

Sade means plain, simple, or without extra ingredients.

So sade omlet means plain omelet.

In food contexts, sade often means something basic and unflavored:

• sade kahve = plain coffee
• sade pilav = plain rice
• sade omlet = plain omelet

It is a very common food word in Turkish.

That is correct: Turkish often does drop subject pronouns because the verb ending already shows the person.

So tercih ediyorum already means I prefer.

But ben is included here for contrast:

• Kız kardeşim ... seviyor, ben ise ... tercih ediyorum.
• My sister likes ..., but I prefer ...

The speaker says ben to highlight the difference between my sister and me.

Without ben, the sentence would still be grammatical, but the contrast would be a little less strong.

İse adds a sense of contrast, something like:

• as for
• whereas
• but
• on the other hand

So:

• ben ise = I, on the other hand / whereas I

It helps compare two different preferences:

• My sister likes cheesy omelets
• I, however, prefer plain omelets

It is not exactly the same as ama (but), but in many contexts the translation can feel similar.

They are related, but not identical.

• seviyor = likes / loves
• tercih ediyorum = I prefer

So the first clause says what the sister likes, while the second says what the speaker prefers.

This is a natural combination in Turkish:

• X seviyor = X likes it
• Ben ... tercih ediyorum = I prefer ...

Also note the forms:

• sev-iyor = is liking / likes
• tercih ediyor-um = I prefer / I am preferring

In everyday Turkish, the -yor form is used for both present continuous and simple present in many situations, especially with meanings like likes, prefers, is doing.

Because tercih etmek is a common Turkish compound verb.

It is made of:

• tercih = preference / choice
• etmek = to do / to make

Together:

• tercih etmek = to prefer

In the sentence, it appears as:

• tercih ediyorum = I prefer

This pattern is very common in Turkish, especially with words of Arabic or Persian origin:

• yardım etmek = to help
• fark etmek = to notice
• kabul etmek = to accept

So learners often need to get used to these noun + etmek verb combinations.

Because the verb endings show different subjects.

• seviyor = he/she likes
• ediyorum = I prefer

More specifically:

• seviyor has a third-person singular meaning: he/she/it likes
• ediyorum has a first-person singular ending -um: I

That matches the subjects:

• Kız kardeşim = my sister → third person singular
• ben = I → first person singular

So the verbs agree with their subjects.

Turkish does not have articles like English a/an or the.

So:

• omlet can mean an omelet, the omelet, or just omelet, depending on context.

In this sentence, the meaning is general:

• kaşarlı omlet seviyor = she likes cheese omelets / she likes a cheese omelet
• sade omlet tercih ediyorum = I prefer plain omelets / a plain omelet

English must choose an article or plural form, but Turkish often leaves that open unless context makes it specific.

This is a very common learner question.

In Turkish, a definite/specific direct object usually takes the accusative ending:

• omleti

But a general, non-specific, category-type object often appears without the accusative:

• omlet

Here, the sentence is talking about general preference:

• kaşarlı omlet seviyor
• sade omlet tercih ediyorum

This means something like:

• She likes cheese omelets
• I prefer plain omelets

It is about the type of food, not one particular omelet.

If you said:

• Kaşarlı omleti seviyor it would more likely suggest a specific cheese omelet or a more definite object, depending on context.

The -yor form is often introduced as the present continuous, but in real Turkish it does more than that.

Here:

• seviyor
• ediyorum

can express a current/general preference, not only something happening right this second.

So in this sentence, the English translation is naturally:

• My sister likes ...
• I prefer ...

not necessarily:

• My sister is liking ...
• I am preferring ...

Turkish often uses -yor for:

• actions happening now
• habits
• ongoing states
• current preferences

So do not think of -yor as matching only English am/is/are ... -ing.

The basic Turkish word order is often Subject – Object – Verb.

That is what you see here:

1. Kız kardeşim = subject
2. kaşarlı omlet = object
3. seviyor = verb

and then:

1. ben ise = subject with contrast
2. sade omlet = object
3. tercih ediyorum = verb

So Turkish usually puts the verb at the end of the clause.

Also notice that descriptive words come before the noun:

• kaşarlı omlet
• sade omlet

That part is similar to English:

• cheesy omelet
• plain omelet

Yes. Turkish allows several natural variations depending on emphasis.

For example:

• Kız kardeşim kaşarlı omlet seviyor, ben sade omlet tercih ediyorum.
• Kız kardeşim kaşarlı omlet seviyor; bense sade omlet tercih ediyorum.
• Ben ise sade omlet tercih ediyorum, kız kardeşim kaşarlı omlet seviyor.

These all keep the same core meaning, but the emphasis changes slightly.

A few notes:

• ben ise sounds a bit more explicitly contrastive
• bense is a very common contracted form of ben ise
• changing the order can shift the focus, but the original sentence is perfectly natural and clear

Almost, but not perfectly.

In everyday translation, kaşarlı omlet is usually best rendered as cheese omelet.

However, kaşarlı specifically refers to kaşar cheese, a particular kind of cheese common in Turkey. So the Turkish phrase can be more specific than the English one.

In many learning contexts, though, cheese omelet is the most natural translation.
