Delight worker behind space next to church (7)
I believe the answer is:
enchant
'delight' is the definition.
(enchant can mean to charm or delight)
'worker behind space next to church' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'behind' says to put letters next to each other.
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
'next to' is a charade indicator (letters next to each other).
'church' becomes 'ch' (abbreviation on maps etc).
'en'+'ch'='ench'
'ant' put after 'ench' is 'ENCHANT'.
(Other definitions for enchant that I've seen before include "Appeal" , "Bewitch, charm" , "Delight, charm" , "Beguile" , "Delight or bewitch" .)
