Carped absurdly, as a military police officer (6)
I believe the answer is:
redcap
'a military police officer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'carped absurdly' is the wordplay.
'absurdly' is an anagram indicator.
'carped' with letters rearranged gives 'REDCAP'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for redcap that I've seen before include "MP" , "Military policeman (slang)" , "Mil. policeman (colloq.)" , "Goldfinch" , "Hole from explosion" .)
