Listens out for recruits (7)
I believe the answer is:
enlists
'recruits' is the definition.
(enlisting is a kind of recruiting)
'listens out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'listens' anagrammed gives 'ENLISTS'.
'for' is the link.
(Other definitions for enlists that I've seen before include "Recruits" , "volunteers" , "Signs up" , "Registers" , "Listens (anag.)" .)
