Was he cured? (5)
I believe the answer is:
bacon
'was he cured?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'was he' is the wordplay.
I cannot really 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 understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bacon that I've seen before include "Francis --, Irish painter" , "Artist - meat" , "Shakespeare's ghost, some say" , "sizzler" , "Thin slices of pig" .)
