He may be cured (5)
I believe the answer is:
bacon
'he may be cured' 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 quite understand how this works, but
'he' could be 'con' and 'con' is present in the answer.
The remaining letters 'ba' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bacon that I've seen before include "Meat (brought home by a breadwinner?)" , "Bring home the ....., achieve success" , "Dried or smoked pig meat" , "sizzler" , "Old scientist" .)
