Kız kardeşim naneli sakız seviyor.

Turkish often expresses sister as kız kardeş, literally girl sibling.

• kardeş = sibling
• kız kardeş = sister
• erkek kardeş = brother

Then -im is added to show my:

• kız kardeşim = my sister

So the structure is basically:

• kız kardeş
  • -im → kız kardeşim

This is very natural Turkish.

The ending -im is a possessive suffix meaning my.

So:

• kardeş = sibling
• kardeşim = my sibling
• kız kardeşim = my sister

Turkish usually shows possession with endings rather than separate words like my, your, his, etc.

A few related examples:

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

Because the possessive ending already shows it.

• kız kardeşim already means my sister
• You do not need benim unless you want emphasis or contrast

So:

• Kız kardeşim naneli sakız seviyor. = My sister likes mint gum.
• Benim kız kardeşim naneli sakız seviyor. = My sister likes mint gum.
  This sounds more emphatic, like contrasting her with someone else.

nane means mint.

The ending -li / -lı / -lu / -lü often means with, having, or flavored with.

So:

• nane = mint
• naneli = minty / with mint / mint-flavored

Therefore:

• naneli sakız = mint gum

This pattern is very common:

• sütlü kahve = coffee with milk / milky coffee
• şekerli çay = tea with sugar / sweetened tea
• peynirli börek = pastry with cheese

Yes. Turkish basic word order is usually Subject – Object – Verb.

In this sentence:

• Kız kardeşim = subject
• naneli sakız = object
• seviyor = verb

So literally it is:

• My sister mint gum likes

That is normal Turkish word order.

English usually prefers Subject – Verb – Object:

• My sister likes mint gum

Both can be possible, but they feel a little different.

• seviyor = is liking / likes
• sever = likes, generally / habitually

With verbs like sevmek (to like / love), Turkish very often uses -iyor in everyday speech even when English uses simple present.

So:

• Kız kardeşim naneli sakız seviyor. = My sister likes mint gum.
• Kız kardeşim naneli sakız sever. = My sister likes mint gum / tends to like mint gum.

Very roughly:

• seviyor can sound more immediate, current, or conversational
• sever can sound more general, habitual, or neutral

In many everyday contexts, seviyor is extremely natural.

Because Turkish and English do not use their tense forms in exactly the same way.

The Turkish -iyor form often covers meanings that English expresses with either:

• is ...-ing
• or the simple present

With a stative verb like sevmek (to like/love), English normally says likes, not is liking.

So although seviyor is built with the -iyor form, the natural English translation is:

• likes

not usually:

• is liking

Good question. In Turkish, a direct object is often:

• unmarked if it is indefinite or generic
• marked with accusative if it is definite/specific

Here:

• naneli sakız seviyor = likes mint gum / likes mint-flavored gum in general

The object is general, not a specific piece of gum, so sakız stays unmarked.

Compare:

• Naneli sakız seviyor. = She likes mint gum.
• Naneli sakızı seviyor. = She likes the mint gum. / She likes that specific mint gum.

So the lack of accusative here is normal and meaningful.

No. kız kardeş just means sister.

If Turkish needs to specify age, it uses extra words such as:

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

So by itself:

• kız kardeşim = my sister

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

A simple approximate pronunciation is:

kuhz kar-deh-sheem na-neh-lee sa-kuhz seh-vee-yor

A few important sounds:

• ı in kız and sakız is not like English i.
  It is a relaxed, back vowel with no exact English equivalent.
• ş is like English sh.
• e is usually like e in bed, but cleaner and shorter.
• r in Turkish is lightly rolled or tapped.
• yor in seviyor is pronounced clearly: yor, not like English your.

If you want, you can think of the rhythm as:

KIZ kar-DE-şim na-NE-li sa-KIZ se-VI-yor

This is the most neutral order, but Turkish can move things around for emphasis.

Neutral:

• Kız kardeşim naneli sakız seviyor.

Possible variations:

• Naneli sakız kız kardeşim seviyor.
• Seviyor kız kardeşim naneli sakız.
  This would be much more marked and context-dependent.

Turkish word order is flexible, but the standard learner-friendly pattern is still:

• subject + object + verb

So the original sentence is the best basic model.

Yes. The dictionary form is sevmek = to like / to love.

To get seviyor:

1. Start with the verb stem: sev-
2. Add the -iyor present/progressive ending
3. For he/she/it, no extra personal ending is needed here

So:

• sev-
  • -iyor → seviyor

Some related forms:

• seviyorum = I like / I am liking
• seviyorsun = you like
• seviyor = he/she likes
• seviyoruz = we like

Yes. That is exactly the idea.

• sakız = gum
• naneli sakız = mint gum / mint-flavored gum / gum with mint flavor

English may translate it in different ways depending on context, but the Turkish phrase naturally refers to gum that has mint flavor.
