Azerbaijani: üçün üç+ün
Means: because of
So, can somebody explain how this is possible?
It is not possible that üçün has been made using üç+ün
We don't have ün/un suffix in Turkic.
I think it was like "O çun" means "because of that" and cause of accent transformed to "üçün", cause you know in Turkic we can't have O and Ü together in one word.
