Süt ve sütü içiyorum? 
What is correct? I think sütü because this is in accusative. 
Are a, e, u, ü, i, ı suffixes for accusative or? 
Thanks 

• MY FIRST MESSAGE,I HOPE I WON´T MESS UP AT THE BEGINING 

• Süt içiyorum - I am  drinking milk ,the answer of "what are you doing now" OR we sometimes use present continuous to mean aorist  so this sentence can also  mean  "I drink milk" (general) another example for this "Her gün tv izliyorum - Everyday I watch TV"

• Sütü içiyorum - I am drinking the milk - there is accusative form and the object is particular, you are drinking the milk which you hv mentioned or the person u r talking to already knows the milk

•  ■ Both are gramatically  correct , so we must look at the  text they are used in to decide which one is correct

Thanks 

Do you know, are a, e, u, ü, i, ı suffixes for accusative or? 

-a and -e are not for accusative they are for dative form which  means TO , but -i -ı -u and -ü are for acusative  

Thanks
