Cover corrupt cops' names (9)
I believe the answer is:
encompass
'cover' is the definition.
(synonyms)
'corrupt cops' names' is the wordplay.
'corrupt' indicates an anagram (a corrupted spelling of the word).
'cops'+'names'='copsnames'
'copsnames' anagrammed gives 'ENCOMPASS'.
(Other definitions for encompass that I've seen before include "Contain or encircle" , "Comprehensively include" , "Comprehend" , "Embrace" , "Contrive" .)
