Questions & Answers about Konferansın ajandasını hazırlayacak birini arıyorum.
How does hazırlayacak mean "who will prepare" without a word for "who"?
In Turkish, relative clauses are made by turning verbs into adjectives using participle suffixes. Here, the future suffix -ecek/-acak is added to hazırlamak (to prepare). So, hazırlayacak literally translates to "will-prepare" and acts as an adjective describing the noun right after it (birini).
If I wanted to say "someone who prepares" (present tense), how would this change?
You would use the present subject participle suffix -(y)An instead of the future one. The word would become hazırlayan, making the phrase hazırlayan birini (someone who prepares). We use hazırlayacak here because the context requires the future meaning.
Why does ajandasını have the -sını ending?
It shows both possession and the direct object. "The conference's agenda" is konferansın ajandası (a genitive-possessive construction). Because this agenda is the specific thing being prepared, it also needs the accusative case suffix -ı. The buffer letter -n- connects them, resulting in ajandası + n + ı = ajandasını.
Why is it birini instead of just biri? "Someone" doesn't feel like a specific direct object here.
