He doesn't have anybody to play with (7)
I believe the answer is:
soloist
'he doesn't have anybody to play with' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really understand how this works, but
'he' could be 'sol' and 'sol' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for soloist that I've seen before include "Virtuoso player" , "One who performs" , "Main singer" , "Only one playing" , "Single performer" .)
