Novel then can charm (7)
I believe the answer is:
enchant
'charm' is the definition.
(synonyms)
'novel then can' is the wordplay.
'novel' indicates anagramming the letters (letters in a new or novel order).
'then'+'can'='thencan'
'thencan' anagrammed gives 'ENCHANT'.
(Other definitions for enchant that I've seen before include "Delight, charm" , "Captivate, charm" , "Fascinate - delight" , "Delight or bewitch" , "Delight, cast spell over" .)
