Learn Turkish: Kameraya dönerek poz vermelisin. - You must pose turning toward the camera.

The word dönerek is made of the verb root dön- (to turn) and the suffix -erek (which means "by doing" or "while doing"). This suffix links two actions, showing how the main action is done. Here, it tells us how you should pose: "by turning" toward the camera.

Why is it Kameraya and not just Kamera?

When you turn to or toward something in Turkish, the destination takes the dative case suffix (-e or -a). Since kamera ends in a vowel, it needs the buffer letter y, becoming kameraya (to the camera).

Why is the verb vermelisin (you must give) used here for "posing"?

In Turkish, there isn't a single common verb for "to pose." Instead, you use the phrase poz vermek, which literally means "to give a pose."

What makes up the word vermelisin?

It breaks down into three parts: the verb root ver- (give), the necessity suffix -meli (must / have to), and the "you" personal ending -sin. Put together, it means "you must give."
