Brown vehicle under which unfortunate male is trapped (7)
I believe the answer is:
caramel
'brown' is the definition.
(I know that caramel is a type of brown)
'vehicle under which unfortunate male is trapped' is the wordplay.
I cannot really see how this works, but
'vehicle' could be 'car' (car is a kind of vehicle) and 'car' is found in the answer.
an anagram of 'male' is 'amel' which is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for caramel that I've seen before include "Sugar solution heated till brown" , "Burnt sugar used for flavouring" , "Cooked sugar" , "Soft sweet" , "Shade" .)
