When the car comes in give a wave Fathers home (8)
I believe the answer is:
'home' is the definition.
(vicarage is a kind of home)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for vicarage that I've seen before include "House of a member of the clergy" , "house near church?" , "Church accommodation" , "Revs will get one such home" , "House of a C of E clergyman" .)
