Wise men caught in wizardry (5)
I believe the answer is:
magic
'wizardry' is the definition.
(I've seen this before)
'wise men caught' is the wordplay.
'wise men' becomes 'magi' (the three wise men from the nativity).
'caught' becomes 'c' (cricket abbreviation).
'magi'+'c'='MAGIC'
'in' acts as a link.
(Other definitions for magic that I've seen before include "Art that supposedly invokes supernatural powers" , "Necromancy" , "Prestidigitation" , "Mysterious quality" , "Spelling?" .)
