Entices to break the rules (5)
I believe the answer is:
lures
'entices' is the definition.
('lure' can be a synonym of 'entice')
'break the rules' is the wordplay.
'break' indicates anagramming the letters.
'rules' anagrammed gives 'LURES'.
'to' is the link.
(Other definitions for lures that I've seen before include "Rules with decoys" , "Draws" , "Baits or attractions" , "Tempts or entices" , "Baits, decoys" .)
