Enchanting person's publication — the Guardian? (5)
I believe the answer is:
magus
'enchanting person's' is the definition.
'magus' can be an answer for 'person's' (magus is a kind of person). I'm not sure about the 'enchanting' bit.
'publication the guardian?' is the wordplay.
'publication' becomes 'mag' (abbreviation for magazine).
'the guardian?' becomes 'us' (the crossword setter and their Guardian colleagues).
'mag'+'us'='MAGUS'
Can you help me to learn more?
(Other definitions for magus that I've seen before include "Sorcerer" , "Magician, wise man" , "Balthazar, Gaspar or Melchior individually" , "Priest" , "Gift-bearing Wise Man" .)
