Litter, perhaps? It’s a lie (9)
I believe the answer is:
stretcher
'litter' is the definition.
(stretcher is a kind of litter)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for stretcher that I've seen before include "Litter for ill people" , "One making economies" , "that can carry some cases" , "Litter for the wounded" , "Horizontal crossbar on a chair" .)
