Flood wolf? (8)
I believe the answer is:
overflow
This clue might be a double definition.
'flood' is the first definition.
(synonyms)
'wolf?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for overflow that I've seen before include "Be excessively full" , "Pipe to remove excess liquid" , "(Outlet for) surplus water" , "Drainage outlet" , "Spillage of excess liquid" .)
