Charm of northern church apprehended by English worker (7)
I believe the answer is:
enchant
'charm' is the definition.
(I know that charm can be written as enchant)
'northern church apprehended by english worker' is the wordplay.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'church' becomes 'ch' (common abbreviation).
'apprehended by' says to put letters next to each other.
'english' becomes 'E' (abbreviation).
'worker' becomes 'ant' (worker is a type of ant).
'n'+'ch'='nch'
'nch' after 'e' is 'ench'.
'ench'+'ant'='ENCHANT'
'of' acts as a link.
(Other definitions for enchant that I've seen before include "transport" , "Hypnotise" , "Delight or bewitch" , "Bewitch, charm" , "Delight, charm" .)
