Car from Finland reversing into field (9)
I believe the answer is:
limousine
'car' is the definition.
(limousine is a kind of car)
'finland reversing into field' is the wordplay.
'finland' becomes 'Suomi' (Finnish name for Finland).
'reversing' is a reversal indicator.
'into' is an insertion indicator.
'field' becomes 'line' (both can refer to an industry or area of expertise).
'suomi' reversed gives 'imous'.
'imous' inserted within 'line' is 'LIMOUSINE'.
'from' acts as a link.
(Other definitions for limousine that I've seen before include "big car" , "Luxurious car (with a chauffeur?)" , "Luxury car" , "Large luxurious car" , "vehicle" .)
