Questions & Answers about Planlanan galanın organizatörü nerede?
How exactly is planlanan formed from the verb planlamak?
The root is planla- (to plan). Because it ends in a vowel, it takes the passive suffix -n instead of -ıl or -in, becoming planlan- (to be planned). Then we add the subject relative participle -an to get planlanan (the planned / that which is planned).
Since someone else planned the gala, shouldn't we use the object participle (-dığı) instead of -an?
If we kept the verb active, we would! For example, planladığım gala means "the gala that I planned". But here, the verb is passive (planlan-). In a passive verb, the thing receiving the action becomes the grammatical subject. Since "the gala" is the subject of "being planned", we must use the subject participle -an.
Why does it say galanın organizatörü instead of just gala organizatörü?
gala organizatörü is an indefinite noun compound meaning a generic "gala organizer" (a profession or type). Because this sentence refers to the organizer of one specific gala, it requires the definite genitive-possessive construction: galanın (of the gala) organizatörü (its organizer).
