Bottom pinched by admirer, one checking for dodgy characters? (9)
I believe the answer is:
subeditor
'one checking for dodgy characters?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'bottom pinched by admirer' is the wordplay.
'bottom' becomes 'bed' (synonyms).
'pinched by' indicates putting letters inside (inserted letters get pinched or taken).
'admirer' becomes 'suitor' (suitor is a kind of admirer).
'bed' going inside 'suitor' is 'SUBEDITOR'.
Can you help me to learn more?
(Other definitions for subeditor that I've seen before include "Employee on paper" , "newspaper role" , "Newspaper worker" , "one makes the headlines" , "News employee" .)
