Sent out traps (4)
I believe the answer is:
nets
'traps' is the definition.
(I know this)
'sent out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'sent' anagrammed gives 'NETS'.
(Other definitions for nets that I've seen before include "Brings home" , "Meshes to catch fish, say" , "Practice pitches (cricket)" , "Cricket practice venue" , "Traps, to catch fish say" .)
