"A bottle of water please."

[DanMan101]

Should "Bitane şişe su lütfen" be accepted?

[AlexinNotTurkey]

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?

[AlexinNotTurkey]

Yep

[danadalloway]

Why not şişede? Because it is a compound noun?
