Questions & Answers about Yeni reklam afişinde markanın logo ve simgesi birlikte yer alıyor.

How is afişinde built up, and what does each part mean?

afişinde = afiş (poster) + -i (3rd-person possessive/definiteness marker) + -nde (locative case “in”).
So literally afiş-i-nde means “in the poster” (here “the new ad poster”).

Why do we need the -i before the locative -nde? I thought locative was just -de or -da.

In Turkish, when you attach a case ending (like locative -de/-da) to a definite noun, you normally add the 3rd-person possessive suffix -i first. It isn’t really a “possessor” here but marks definiteness (“the poster”) and allows you to say “in the poster” rather than “in a poster.”
Without it, afişte could be “in a poster” (indefinite).

What role does markanın play? Is that the genitive case?

Yes. markanın = marka (brand) + -nın (genitive case, harmonizing to -ın) = “of the brand.” It marks marka as the possessor in the genitive–possessive construction.

If markanın is the possessor, why is only simgesi marked with a possessive suffix and not logo?
