Questions & Answers about Öğrenci kırmızı bir elma yiyor.
Why is it kırmızı bir elma instead of bir kırmızı elma?
Does the adjective kırmızı need any special endings to match the noun?
No! Unlike in some other languages, Turkish adjectives do not change. They never take plural endings or case markers to match the noun they describe. They just sit right before the noun in their plain dictionary form.
The apple is the object being eaten. Why isn't it written as elmayı?
You only use the specific direct object ending (the accusative case) when you are talking about a specific object, like 'the red apple'. Because the student is eating an unspecified apple (bir elma), it stays in its plain form without a case suffix.
The dictionary form of 'to eat' is yemek. Why does it change to yiyor here?
