Temptations to break the rules? (5)
I believe the answer is:
lures
'temptations' is the definition.
(I know this)
'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 "Baits or attractions" , "Baits, decoys" , "Draws" , "Tempts or entices" , "Rules with decoys" .)
