Husband at church with second car (9)
I believe the answer is:
hatchback
'car' is the definition.
(hatchback is a kind of car)
'husband at church with second' is the wordplay.
'husband' becomes 'h'.
'church' becomes 'ch' (common abbreviation).
'with' says to put letters next to each other.
'second' becomes 'back' (to second a motion is to back it).
'h'+'at'+'ch'+'back'='HATCHBACK'
(Other definitions for hatchback that I've seen before include "Vehicle" , "Type of car with sloping rear car door" , "Style of '5-door' car" , "Car with sloping rear boot" , "transport" .)
