Learn Turkish: Görevli bana giriş ücretini nereye ödeyeceğimi anlatıyor. - The attendant is explaining to me where I will pay the entrance fee.

This is how Turkish forms indirect Wh-questions. It pairs the question word nereye (where to) with a factive clause. The verb ödemek (to pay) takes the future suffix -(y)ecek and the 1st person possessive -im (my). Literally, the structure translates to something like "my future paying to where".

Why is there an extra "-i" at the end of "ödeyeceğim"?

The verb anlatmak (to explain) requires the accusative case for the thing being explained. Here, the entire indirect question "where I will pay" (nereye ödeyeceğim) acts as the specific direct object of anlatıyor. Therefore, it needs the accusative suffix -i, making it ödeyeceğimi.

Why do we use "nereye" (to where) instead of "nerede" (at where) for paying?

In English, we usually talk about paying at a counter or in a location. In Turkish, handing over money is often treated as an action directed toward a destination or recipient. Because of this sense of motion or transfer, ödemek (to pay) naturally pairs with the dative question word nereye.

Why does "giriş ücretini" end with "-ni" instead of just "-i" for the accusative?
