An enticement (4)
I believe the answer is:
bait
'an enticement' is the definition.
(bait is a kind of enticement)
This is all the clue.
(Other definitions for bait that I've seen before include "Lure; deliberately taunt" , "Used to lure fish or other animals into danger" , "Deliberately annoy or taunt" , "A lure to catch fish" , "Food to lure fish" .)
