Damage carts, possibly, going to church (7)
I believe the answer is:
scratch
'damage' is the definition.
(I have seen 'superficial damage' mean 'scratch' so perhaps 'damage' could also mean 'scratch')
'carts possibly going to church' is the wordplay.
'possibly' indicates anagramming the letters.
'going to' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'carts' anagrammed gives 'scrat'.
'scrat'+'ch'='SCRATCH'
(Other definitions for scratch that I've seen before include "minor injury" , "Deal with itch - cancel entry" , "Superficial damage; withdraw" , "Scrape" , "Score with a sharp object" .)
