Man left in – he made people laugh (7)
I believe the answer is:
chaplin
'he made people laugh' is the definition.
The definition suggests a singular noun which matches the answer.
'man left in' is the wordplay.
'man' becomes 'chap' (term for a man).
'left' becomes 'l' (common abbreviation).
'chap'+'l'+'in'='CHAPLIN'
Can you help me to learn more?
(Other definitions for chaplin that I've seen before include "Charles, early film actor and director" , "English silent comedy actor, d. 1977" , "Charlie ......., popular tramp of silent screen" , "Charles, film star and director" , "Charlie, immortal cinema clown" .)
