Fishing decoy (4)
I believe the answer is:
lure
'fishing decoy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lure that I've seen before include "Attract with bait" , "It's used to attract fish" , "'Entice, tempt (4)'" , "'Decoy, bait (4)'" , "Enticement" .)
