Sean home to drive a car (5)
I believe the answer is:
sedan
'a car' is the definition.
(sedan is a kind of car)
'sean home to drive' is the wordplay.
'home to' indicates putting letters inside (some letters house or home others).
'drive' becomes 'd' (this could be a standard abbreviation of which I'm unaware).
'sean' going around 'd' is 'SEDAN'.
Can you help me to learn more?
(Other definitions for sedan that I've seen before include "Chair; car" , "Dean's in an old conveyance" , "Covered chair carried between poles" , "Saloon car in America" , "Chair to be carried by two" .)
