Rules out temptations (5)
I believe the answer is:
lures
'temptations' is the definition.
(I know this)
'rules out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'rules' with letters rearranged gives 'LURES'.
(Other definitions for lures that I've seen before include "Tempts or entices" , "Baits, decoys" , "Draws" , "Baits or attractions" , "Rules with decoys" .)
