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 see how this works, but
'he' could be 'con' and 'con' is found within the answer.
The remaining letters 'ba' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
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" .)
