Teyzem akşam için peynirli börek açıyor, ev mis gibi kokuyor.

Teyze means maternal aunt (your mother’s sister). The -m is the 1st person singular possessive ending, so:

• teyze = aunt
• teyzem = my aunt

This is very common in Turkish:

• annem = my mother
• babam = my father
• ablam = my older sister

So teyzem is literally my aunt.

No. Turkish often distinguishes family relationships more specifically than English.

• teyze = mother’s sister
• hala = father’s sister

So teyzem specifically means my mother’s sister.

Akşam means evening (and sometimes evening meal / dinner time, depending on context).
İçin means for.

So akşam için means:

• for the evening
• for tonight
• sometimes naturally in English: for dinner / for this evening

In this sentence, it suggests your aunt is making the börek for later in the evening, not necessarily eating it right now.

The suffix -li / -lı / -lu / -lü means with, containing, or having.

So:

• peynir = cheese
• peynirli = with cheese / cheese-filled / cheesy

Other examples:

• şekerli çay = tea with sugar
• sütlü kahve = coffee with milk
• zeytinli poğaça = pastry with olives

So peynirli börek means cheese börek or börek with cheese.

Yes, açmak very often means to open, but it has several related meanings. In cooking, hamur açmak means to roll out dough.

With börek, börek açmak usually means:

• to prepare börek by rolling out the dough
• to make homemade börek from scratch

So this is not just opening something literally. It refers to the traditional process of making thin pastry sheets.

This is a good example of how a very common Turkish verb can have a specialized meaning in context.

Açıyor is the present continuous form of açmak.

Structure:

• verb stem: aç-
• present continuous: -ıyor
• açıyor = is opening / is rolling out / is making

In this sentence, it means your aunt is currently making the börek.

The Turkish -yor tense often corresponds to English:

• is doing
• is making
• sometimes even does / is about to do, depending on context

Here the most natural translation is something like My aunt is making cheese börek for the evening.

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

So instead of saying:

• Teyzem o peynirli börek açıyor

Turkish normally just says:

• Teyzem peynirli börek açıyor

The noun teyzem already tells you who is doing the action, so o (she) is unnecessary.

This is very normal in Turkish.

Mis gibi is a very common expression meaning:

• wonderfully
• deliciously
• beautifully
• fresh and lovely-smelling

With kokmak (to smell), it usually means smelling absolutely wonderful.

So:

• Ev mis gibi kokuyor = The house smells wonderful

It is partly idiomatic. Historically mis is related to musk, a pleasant scent, but in modern Turkish learners usually just need to recognize mis gibi as a fixed expression meaning something like lovely / wonderfully / deliciously.

You can hear it in lots of contexts:

• Mis gibi kahve kokuyor. = It smells like wonderful coffee.
• Mis gibi hava var. = The air/weather is lovely and fresh.
• Mis gibi olmuş. = It turned out beautifully / perfectly.

Because ev is the subject of the second clause.

• ev = house / home
• ev kokuyor = the house smells

If you said evi, that would usually mark it as a definite object in another structure, which is not what is happening here.

So in:

• ev mis gibi kokuyor

the house is the thing doing the smelling, grammatically speaking.

Yes, this is normal. The sentence has two related statements:

1. Teyzem akşam için peynirli börek açıyor
2. ev mis gibi kokuyor

Together they create a natural little scene:

• My aunt is making cheese börek for the evening,
• and the house smells wonderful.

In English, you might prefer:

• My aunt is making cheese börek for the evening, and the house smells wonderful.

Turkish often connects closely related thoughts this way, especially in everyday language.

Yes, depending on context, akşam can suggest both evening and the evening meal / dinner time.

So akşam için could be understood as:

• for the evening
• for tonight
• for dinner

If the meaning has already been shown to the learner, the important thing is that the Turkish phrase points to something being prepared for later that evening.

Often, yes. Börek is a very common Turkish pastry made with thin dough or yufka, often filled with things like:

• cheese
• minced meat
• potatoes
• spinach

In many learning materials, it is better to keep börek as börek rather than force a rough translation like pastry or pie, because those English words are only approximate.

So peynirli börek is often best understood as:

• cheese börek
• or, if needed, a savory Turkish pastry with cheese

A fairly literal translation would be:

My maternal aunt is rolling out/making cheese börek for the evening; the house smells wonderfully.

A more natural English version would be:

My aunt is making cheese börek for tonight, and the house smells amazing.

So the Turkish is very vivid and domestic: someone is cooking, and the smell fills the house.
