Kız arkadaşım yazın genellikle etek giyiyor.

It can mean either my girlfriend or my female friend, depending on context.

• kız = girl
• arkadaş = friend
• arkadaşım = my friend

In everyday modern Turkish, kız arkadaşım very often means my girlfriend. But literally it can also mean my female friend. Context tells you which meaning is intended.

-ım is the 1st person singular possessive suffix, meaning my.

So:

• arkadaş = friend
• arkadaşım = my friend

Because Turkish often uses possessive suffixes instead of separate words like my, the meaning is built into the noun itself.

Because kız is modifying arkadaşım as a noun phrase.

• kız arkadaş = girlfriend / female friend
• kız arkadaşım = my girlfriend / my female friend

Turkish often forms expressions like this with two separate words rather than one combined word.

Here, yazın means in summer or during the summer.

• yaz = summer
• yazın = in summer

This is a very common time expression in Turkish. In this sentence, it tells you when the action usually happens.

For seasons and general time expressions, Turkish often uses special adverbial forms like yazın, kışın, etc.

So:

• yazın = in summer
• kışın = in winter

These are natural, common ways to talk about seasons in a general sense. A learner might expect a regular case ending, but in this kind of time expression, yazın is the usual form.

Genellikle means generally, usually, or in general.

In this sentence, it shows that this is a habit or typical behavior, not just a one-time action.

So the sentence is talking about what she usually wears in summer.

Turkish word order is flexible, but adverbs like genellikle often come before the main verb and after time expressions.

So this order is very natural:

• Kız arkadaşım = my girlfriend
• yazın = in summer
• genellikle = usually
• etek = skirt
• giyiyor = wears / is wearing

A very literal structure would be:

My girlfriend, in summer, usually skirt wears.

The verb normally comes at the end in Turkish.

Turkish often uses the singular form when English might use singular or plural in a general sense.

So etek giyiyor can naturally mean:

• she wears a skirt
• she wears skirts

The exact English translation depends on context and style, but the Turkish sentence is completely natural with singular etek.

In this sentence, it means a habit: she usually wears a skirt in summer.

Even though -iyor is often introduced as the present continuous (is wearing), in Turkish it is also commonly used for regular habits and repeated actions.

Because of yazın and genellikle, the habitual meaning is clear.

giyiyor comes from the verb giymek, which means to wear or to put on.

Breakdown:

• giy- = verb stem
• -iyor = present continuous / ongoing present marker

So giyiyor means:

• he/she is wearing
• he/she wears
  depending on context

In this sentence, it is understood as she usually wears.

Because Turkish often leaves subject pronouns out when they are clear from context.

Here, the subject is already stated as kız arkadaşım, so there is no need to add o (he/she/it).

Turkish avoids unnecessary pronouns much more than English does.

In the 3rd person singular, Turkish verbs often have no extra personal ending beyond the tense marker.

So:

• giyiyorum = I am wearing
• giyiyorsun = you are wearing
• giyiyor = he/she is wearing

That is why giyiyor by itself can mean he is wearing or she is wearing.

The basic order is:

Subject + Time + Adverb + Object + Verb

So:

• Kız arkadaşım = subject
• yazın = time expression
• genellikle = adverb
• etek = object
• giyiyor = verb

This is a very normal Turkish sentence pattern, especially because the verb usually comes last.

Yes, Turkish allows some flexibility in word order, especially for emphasis. But the original sentence is the most neutral and natural for a learner.

For example, different word orders could emphasize different parts, but:

Kız arkadaşım yazın genellikle etek giyiyor.

is a straightforward, standard version.

No. Turkish does not have articles like a/an and the.

So etek by itself can mean:

• a skirt
• the skirt
• skirts
  depending on context

Here, the most natural English translation is usually a skirt or skirts.

It is most commonly used for wearing clothes, but it can also be used for things you put on the body, such as:

• şapka giyiyor = wearing a hat
• ceket giyiyor = wearing a jacket

Turkish also uses related verbs in some contexts, but giymek is the main verb for wear/put on clothing.

The dictionary form is giymek.

In Turkish, dictionary verbs usually end in -mek or -mak. So:

• giymek = to wear

In the sentence, that verb appears as giyiyor, which is the present form.

Yes. That is a very good natural translation.

Because Turkish does not always mark singular/plural the same way English does in generic statements, both of these can work:

• My girlfriend usually wears a skirt in summer.
• My girlfriend usually wears skirts in the summer.

The exact English wording depends on what sounds most natural in context.
