Creature found in vehicle I purchased with 50 per cent off (7)
I believe the answer is:
caribou
'creature' is the definition.
(I've seen this before)
'vehicle i purchased with 50 per cent off' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'purchased' becomes 'bought' ('buy' can be a synonym of 'purchase').
'with 50 per cent off' indicates taking half.
'bought' cut in half is 'bou'.
'car'+'i'+'bou'='CARIBOU'
'found in' acts as a link.
(Other definitions for caribou that I've seen before include "N. American reindeer" , "N.American reindeer" , "North American Arctic deer" , "Large North American deer" , "Creature" .)
