Luxury vehicle - left one rodent in interior (9)
I believe the answer is:
limousine
'luxury vehicle' is the definition.
'limousine' can be an answer for 'vehicle' (limousine is a kind of vehicle). I am unsure of the 'luxury' bit.
'left one rodent in interior' is the wordplay.
'left' becomes 'l' (common abbreviation).
'one' becomes 'i' (Roman numeral).
'rodent' becomes 'mouse' (mouse is a kind of rodent).
'interior' is an insertion indicator.
'mouse' placed around 'in' is 'mousine'.
'l'+'i'+'mousine'='LIMOUSINE'
Can you help me to learn more?
(Other definitions for limousine that I've seen before include "Luxurious car (with a chauffeur?)" , "Large luxurious car" , "big car" , "Luxury car" , "vehicle" .)
