"The last day"

[KALKSINordekler]

Why is it "son gun" and not "son gunu"?

[AlexinNotTurkey]

"son" is an adjective and therefore does not form noun compounds. :)

And just to cover my bases (if you are thinking about this), only specific direct objects take the accusative case. Subjects and independent words never will.

I thought it meant "the end of the day" would it be "günün sonu"?
