Lift to reveal wreckage (8)
I believe the answer is:
elevator
'lift' is the definition.
(I know that lift can be written as elevator)
'to reveal wreckage' is the wordplay.
'wreckage' indicates an anagram (I've seen this in other clues).
'to'+'reveal'='toreveal'
'toreveal' with letters rearranged gives 'ELEVATOR'.
(Other definitions for elevator that I've seen before include "may give you a lift" , "part of tail muscle" , "what makes flight unnecessary" , "North American lift" , "Cage that is raised and lowered mechanically in a vertical shaft" .)
