Gibson left after me (3)
I believe the answer is:
'gibson' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I can't see?
'left after me' is the wordplay.
'left' becomes 'l' (common abbreviation).
'after' means one lot of letters go next to another.
'l' 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)" .)
