Father has maybe one old possible banger after another (5)
I believe the answer is:
vicar
'father has' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'one old possible banger after another' is the wordplay.
'one old possible banger' becomes 'vi' (I am not sure about this - if you are sure you should believe this answer much more).
'after' says to put letters next to each other.
'another' becomes 'car' (I've seen this in other clues).
'vi'+'car'='VICAR'
'maybe' is the link.
Can you help me to learn more?
(Other definitions for vicar that I've seen before include "Parish priest" , "Parish clergyman" , "one brought in for service?" , "Man with a dog collar" , "Local priest" .)
