Questions & Answers about Komitenin bu kararı veto edeceğine dair bilgi kesin değil.
Why do we use dair here to translate the English word "that"?
In English, you say "information that [something will happen]". Turkish often expresses this as "information regarding the fact that [something will happen]". The postposition dair means "regarding" or "about" and links the embedded future clause to the noun bilgi.
Why does veto edeceğine have a dative ending (-e)?
The postposition dair always requires the preceding word to be in the dative case. The base verb is veto etmek. We add the future participle -(y)AcAk, the 3rd person possessive -i (matching the committee), the buffer -n-, and finally the dative -e to satisfy dair.
Why is the committee marked with the genitive case (Komitenin)?
Komite is the subject of the embedded clause. When forming complement clauses with -dIk or -(y)AcAk, the subject of that action takes the genitive case, and the verb takes a matching possessive suffix. It structurally acts like "The committee's future-vetoing".
Could we use hakkında instead of -e dair in this sentence?
Yes, but the grammar changes slightly because hakkında does not take the dative case. If you used it, you would drop the dative -e and buffer -n-, resulting in Komitenin bu kararı veto edeceği hakkında bilgi kesin değil.
