Two places to find water in Turkey, perhaps (4,6)
I believe the answer is:
main course
'two' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'places to find water in turkey perhaps' is the wordplay.
I cannot really understand how this works, but
'water' could be 'main' (main is a kind of water) and 'main' is found within the answer.
The remaining letters 'course' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for main course that I've seen before include "A lot to take in" , "substantial part of meal" , "Substantial dish" , "Series of sailing lessons" , "Marine biology, perhaps" .)
