Questions & Answers about Kış diye bir melodi çok ritmik ve nostaljik.
I've seen diye used for "because" or "saying". How does it mean "called" here?
In the specific pattern [Name] diye bir [Noun], diye acts as a naming label. While it literally translates to "a melody saying 'Winter'", in Turkish this is the standard colloquial way to say "a melody called 'Winter'".
Could I say Kış adında bir melodi instead?
Is the word bir required in the phrase Kış diye bir melodi?
Why is there no "to be" suffix (like -tir) at the end of nostaljik?
In spoken and everyday written Turkish, the third-person "to be" suffix (-dır / -dir / -tir) is often dropped in simple descriptions. You would add -tir if you were stating an encyclopedic fact or a firm conclusion, but for a casual opinion about a song, just ending with the adjective is perfectly natural.
