Gibson left after me (3)
I believe the answer is:
'gibson' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'left after me' is the wordplay.
'left' becomes 'l' (common abbreviation).
'after' is a charade indicator (letters next to each other).
'l' put after 'me' is 'MEL'.
Can you help me to learn more?
(Other definitions for mel that I've seen before include "-- Brooks, film director" , "Honey" , "- - Gibson (actor)" .)
