Angler's attachment (4)
I believe the answer is:
bait
'angler's attachment' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bait that I've seen before include "Boilie, for example" , "Worms, for example" , "A lure to catch fish" , "Taunt; enticement" , "What lures" .)
