"Sophie'nin arabası" this is a defined noun modification.


Sophie + n + in araba + s +ı
Noun + buffer -n + genitive case -in + noun + buffer -s + noun modification suffix -ı

If you say "Sophie'nin arabasını" :

Sophie + n + in araba + s +ı + n + ı
Noun + buffer -n + genitive case -in + noun + buffer -s + noun modification suffix -ı + buffer -n + accusative case -ı

You need to use a transitive verb with accusative. For instance "anlamak" is a transitive verb. This means it takes an object and we use an object suffix. The object suffix is also called the accusative case suffix.

So we say "-i anlamak" where anlamak takes the accusative (object suffix).

Erdinç'in dersini anlamıyorum.

But, without a transitive verb we don't add the accusative:

Erdinç'in dersi çok açıklayıcı.

Thank you Erdinc for explaining this to me.

Now about the consonants, do p ç t k change when they are in a name and are followed by an apostrophe? Or they stay as they are and change only when an apostrophe is not following?

About accusative I have added an example. Here is another one:

Sophie'nin arabası çok güzel.
No accusative is used since there is no transitive verb (a verb that takes an object. Accusative case suffix is also called object suffix)

Sophie'nin arabasını beğeniyorum.
Accusative is used since there is a transitive verb "beğenmek" (a verb that takes an object). We say "-i beğenmek".

With proper names spelling doesn't change but the pronounciation changes with consonant mutations.

Example:

Burak > Burak'ı
It's spelling is the same but pronounciation needs to be changed. changes.

Notice that with ordinary names both it's spelling and pronounciation changes.
Example:
ekmek > ekmeği

Single syllables are usually exempt from consonant mutation.
example:

Berk > Berk'i
Nor it's spelling or pronounciation changes becaus it is a single syllable.

yat > yatı
kat > katı
çark > çarkı

But there are exepions:
çok > çoğu

Tamam, anladım. çok teşekkür ederim
