Questions & Answers about Oyun yazarı provayı izliyor.
Because Turkish often makes noun compounds by putting two nouns together.
- oyun = game, play
- yazar = writer
- oyun yazarı = playwright, literally play writer
In this kind of compound, the second noun usually takes a possessive-type ending. That is why it is yazarı, not just yazar.
So:
- oyun yazarı = playwright
- similar pattern: Türk kahvesi = Turkish coffee, okul kapısı = school door
It is actually built from yazar + compound ending -(s)I.
Since yazar ends in a consonant, the ending appears as -ı here:
- yazar
- -ı → yazarı
This is the normal form in a noun compound. It does not mean his/her writer in this sentence; it is just part of the compound oyun yazarı.
