why isnt "Bir su şişe , lütfen" eccepted?
I have the same question, can anyone help? Is it because saying "bir su" will imply we're counting the water?
Should "Bitane şişe su lütfen" be accepted?
Nope. First off, you would have to say "bir tane." Saying "bi tane" is slang. However, both "tane" (piece) and "şişe" are words used to count objects and you cannot have two before one noun. :)
Sise means bottle?
Why not şişede? Because it is a compound noun?
