He doesn't go out with his mates (4)
I believe the answer is:
scab
This could be a double definition.
'he doesn't go out' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'his mates' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for scab that I've seen before include "Wound's crust" , "Blackleg, strike-breaker" , "Blackleg - sign of injury" , "Crust forming over wound" , "Crust on wound, or a blackleg" .)
