Silent actor in church - plain wrong (7)
I believe the answer is:
chaplin
'silent actor' is the definition.
The definition suggests a singular noun which matches the answer.
'church plain wrong' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'wrong' indicates an anagram.
'plain' anagrammed gives 'aplin'.
'ch'+'aplin'='CHAPLIN'
'in' is the link.
Can you help me to learn more?
(Other definitions for chaplin that I've seen before include "Old comedian" , "Charlie ---, film comedian" , "Charlie --, silent film star" , "bowler went over this player's head?" , "Charlie --, film comic" .)
