"I do not cook on Fridays."

Translation: Cuma günleri yemek pişirmem.

[Gizella70]

Where is "yemek" from?

[AlexinNotTurkey]

"To cook" is either "yemek pişirmek" or "yemek yapmak." It just simply must be there :)

[JacquelGordon]

why not "cuma günleri pişirmem." ?

[Nursssssss]

Yemek pişirmek is more common than just pisirmek. But your said isn't wrong too.

[adelips]

Why not "cumalarda"?

[joefeyzullah]

İt's uncommon. And it even specifically means on Friday's prayer

[Hakim747]

Why not günlerinde?

[morowinger]

Why can't it say "Cuma gün"?

[SabineBergmann1]

That means on Friday, but it is saying on Fridays

[Nursssssss]

We never say cuma gün. It sounds like ,cuma is an adjective. We say cuma günü but when you say that it is just for one day. Cuma günleri is a general expression-for all fridays

[SabineBergmann1]

yes, that is what I am thinking. But there is a sentence in this lesson saying: Onlar genelde cuma günü okula gitmezler. I think that genelde implies more than one Friday, so I thought it must be Onlar genelde cuma günleri okula gitmezler. But Duoling said to use cuma günleri in this ase is wrong. I don't understand it.

[joefeyzullah]

Your sentence is correct but it's too redundant in daily speech.
