Yarın kuzenimin nikâhı var, bu yüzden annemle gelinlik bakmaya gideceğim.

Kuzenimin breaks down like this:

• kuzen = cousin
• kuzenim = my cousin
• kuzenimin = of my cousin

So the word contains two things:

1. -im = my
2. -in = the genitive ending, which often corresponds to of

That is why kuzenimin nikâhı means my cousin’s wedding/marriage ceremony.

This is because Turkish usually marks both sides of a possession structure.

In English, we say:

• my cousin’s wedding

In Turkish, the pattern is often:

• possessor + genitive
• possessed thing + possessive suffix

So:

• kuzenimin = of my cousin
• nikâhı = his/her wedding ceremony

Together:

• kuzenimin nikâhı

This is a very common Turkish pattern:

• annemin arabası = my mother’s car
• evin kapısı = the door of the house

Not exactly.

• nikâh usually refers to the marriage ceremony itself, often the official or formal act of getting married.
• düğün is the wedding celebration/event more generally.

So nikâh is a bit narrower than düğün.

Depending on context, English might still translate both as wedding, but in Turkish the nuance is different.

Turkish often uses var to say that something exists, is happening, or is scheduled.

So:

• Yarın kuzenimin nikâhı var
  literally feels like
• Tomorrow, my cousin’s wedding ceremony exists / is on

This is a very natural Turkish way to talk about events:

• Yarın toplantı var = There’s a meeting tomorrow
• Akşam ders var = There’s class in the evening

You could sometimes hear olacak in similar situations, but var is extremely common and natural for scheduled events.

Bu yüzden means:

• therefore
• for this reason
• because of this
• so

It connects the first idea to the result:

• Yarın kuzenimin nikâhı var, bu yüzden...
• Tomorrow is my cousin’s wedding ceremony, so...

It is a fixed expression and is very common in everyday Turkish.

Both are correct.

• annem ile
• annemle

The shorter form with -le/-la is very common in speech and writing.

Here:

• annem = my mother
• annemle = with my mother

So -le/-la is the equivalent of with.

More examples:

• arkadaşımla = with my friend
• babamla = with my father

Because Turkish verbs already show the subject.

Gideceğim means:

• I will go

It contains:

• git- = go
• -ecek/-acak = future tense
• -im / -ım type personal ending = I

So Turkish often leaves out ben because it is already clear from the verb.

If you say Ben gideceğim, that usually adds emphasis:

• I will go

Gideceğim is the future tense of gitmek.

Breakdown:

• gitmek = to go
• stem changes to gid- before this tense form
• -ecek = future
• -im = first person singular

So:

• gideceğim = I will go

This is a very common future pattern in Turkish:

• geleceğim = I will come
• yapacağım = I will do
• bakacağım = I will look

This is a very common Turkish structure:

• Verb stem + -maya/-meye + gitmek
• meaning: to go in order to do something

So:

• bakmak = to look
• bakmaya gitmek = to go to look

In smoother English, that often becomes:

• to go look at
• to go shopping for
• to go check out

Other examples:

• yemek yemeye gitmek = to go eat
• alışveriş yapmaya gitmek = to go shopping
• gezmeye gitmek = to go sightseeing / go out घूम? no, better: to go for an outing

So gelinlik bakmaya gideceğim means I will go to look at/shop for wedding dresses.

Because the main verb of the whole action is gitmek = to go.

The looking is the purpose of the going.

So the structure is:

• [purpose action] + [main motion verb]

Here:

• bakmaya = to look / in order to look
• gideceğim = I will go

So the sentence is not saying simply I will look. It is saying I will go to look.

Because gelinlik bakmak is an idiomatic shopping-style expression in Turkish.

It often means:

• to look at wedding dresses
• to shop around for wedding dresses

In Turkish, when talking about shopping or browsing, a bare noun is often used like this.

So:

• gelinlik bakmak = to look for / browse wedding dresses

If you said gelinliğe bakmak, that would sound more like looking at a specific wedding dress.

So the version in the sentence is broader and more natural for shopping.

Turkish word order is flexible, but time expressions very often come early in the sentence.

So:

• Yarın kuzenimin nikâhı var

sounds very natural because it sets the time first:

• Tomorrow...

This is common in Turkish:

• Bugün çok yoğunum = Today I’m very busy
• Yarın okula gideceğim = Tomorrow I will go to school

Putting yarın first helps frame the whole sentence right away.
