Lure away from law (4)
I believe the answer is:
rule
'law' is the definition.
(rule is a kind of law)
'lure away' is the wordplay.
'away' indicates anagramming the letters.
'lure' with letters rearranged gives 'RULE'.
'from' acts as a link.
(Other definitions for rule that I've seen before include "Govern, reign over" , "Regulation, control" , "Reign - law" , "Standard" , "Control, government" .)
