Excess food storage? Fine to be ripped off (4)
I believe the answer is:
lake
'excess' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lake that I've seen before include "Superior maybe < that's red" , "Pool" , "Superior, e.g." , "Mere - organic pigment" , "Water in North Italy" .)
