Learn Turkish: Siz saatçiyi bekleyedurun, ben ayakkabıcıdan paketleri alayım. - You guys keep waiting for the watchmaker, let me get the packages from the shoe store.

It starts with the verb root bekle- (to wait). Since it ends in a vowel, we add the buffer -y-, followed by the continuous action suffix -edur (from -(y)edurmak). Finally, the 2nd person plural imperative suffix -un is added. Together, it commands: "you (plural) keep on waiting."

Does the continuous suffix -(y)edurmak have a special nuance here?

Yes! The compound -(y)edurmak often implies "you keep doing this while something else happens" or "until I get back." It perfectly sets up the second half of the sentence, contrasting the group's ongoing action with the speaker's simultaneous task of getting the packages.

Why is saatçiyi in the accusative case if we are waiting for him?

Unlike English, where you wait for someone, the Turkish verb beklemek takes a direct object. You are directly "waiting the watchmaker," so saatçi gets the specific accusative ending -yi.

Ayakkabıcı literally means "shoemaker", so why is it translated as "shoe store"?

In Turkish, words for professions ending in -cı / -ci are frequently used to refer to the shop or business itself. Just like you might say "I'm getting it from the butcher's" in English, ayakkabıcıdan is the natural way to say "from the shoe store."
