Possibly wee lover (10)
I believe the answer is:
This clue might be a double definition.
'possibly wee' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'lover' is the second definition.
(I know that sweetheart is a type of lover)
Can you help me to learn more?
(Other definitions for sweetheart that I've seen before include "Love" , "Boy- or girlfriend" , "One loved" , "Steady!" , "Dear" .)
