Water supply American provided in Queens? (7)
I believe the answer is:
aquifer
'water' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'american provided in queens?' is the wordplay.
I cannot quite see how this works, but
'american' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is located in the answer.
'provided' could be 'if' (eg 'provided it's sunny' means 'if it's sunny') and 'if' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'supply' is the link.
Can you help me to learn more?
(Other definitions for aquifer that I've seen before include "Water-bearing rock formation" , "Water-bearing stratum of permeable rock" , "Water-carrying layer of rock" , "it holds water" , "Underground source of water" .)
