Will he never quite be a lady's man? (3)
I believe the answer is:
lad
This clue could be a double definition.
'will he never quite be a lady's' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'man?' is the second definition.
(I have seen 'Young man' mean 'lad' so perhaps 'man' could also mean 'lad')
Can you help me to learn more?
(Other definitions for lad that I've seen before include "Chap, fellow" , "(Housman's Shropshire) boy" , "Shaver" , "Boy, familiar" , "Stable employee" .)
