Maria's bowled over after church appeal (8)
I believe the answer is:
charisma
'appeal' is the definition.
(I've seen this in another clue)
'maria's bowled over after church' is the wordplay.
'bowled over' indicates anagramming the letters (letters knocked around or bowled over).
'after' means one lot of letters go next to another.
'church' becomes 'ch' (common abbreviation).
'marias' anagrammed gives 'arisma'.
'arisma' put after 'ch' is 'CHARISMA'.
(Other definitions for charisma that I've seen before include "An individual person's charm" , "attractive quality" , "Allure" , "it inspires loyalty" , "Attraction" .)
