New role for tradition (4)
I believe the answer is:
lore
'for tradition' is the definition.
(I've seen this in another clue)
'new role' is the wordplay.
'new' indicates anagramming the letters.
'role' is an anagram of 'LORE'.
(Other definitions for lore that I've seen before include "Traditional belief" , "Role for learning" , "old-fashioned thong" , "Body of knowledge" , "Old learning" .)
