Learn Turkish: Neden eczaneye gitmen gerek? - Why do you need to go to the pharmacy?

This structure literally translates to "your going is necessary". We take the verb root git- (go), add -me to turn it into a short noun (going), and then add the possessive ending -n (your). Finally, we add the word gerek (necessary).

Can I use lazım instead of gerek here?

Yes! In this grammar structure, gerek and lazım both act as adjectives meaning "necessary" and are entirely interchangeable. You will hear both gitmen gerek and gitmen lazım used to mean "you need to go".

Why is there a -ye at the end of eczaneye?

Because the verb is gitmek (to go), you have to show the direction you are going to. We do this with the dative case. Since eczane (pharmacy) ends in a vowel, we add the buffer letter -y- followed by the ending -e to mean "to the pharmacy".

Where is the word for "you" in this sentence? Should it be sen?
