Translation: Yarınki ders saat beşte.

What is the difference between "ders", "kurs", or" "sinif"?

[orde90]

Ders = course (as a unit), lesson, lecture, class
Sınıf = classroom, section of a class, the people in the classroom.
Kurs = course that doesn't belong to the regular education system. ie. Language courses, driving courses; school that offer such courses

Yarınkı or yarınki

[SeanSmithereens]

'-ki' is an affix that doesn't follow any vowel harmony, so it's the same for every word (except for the exceptions 'dünkü' and 'bugünkü', of course).

[maksym.kurkin]

could one say 'beş saatta'?

[AlexinNotTurkey]

Nope! "saat" always comes first.

As a side note, "saat" is also a bit irregular and would take i/e endings for suffixes (saatte)

thanks!

@alex does beş saatte mean 'in five hours' ?

[maryam534517]

Why saat comes first ?
When we ask 'kaç saat?' The answer comes beş saat
Am i wrong here ?

[orde90]

"Kaç saat?" means "How many hours?". "At what time?" is "Saat kaçta?" So it fits the question.

Well it makes sense now . Teşekkür ederim
