In which to be lifted up? (5)
I believe the answer is:
shaft
'in which to be lifted up?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for shaft that I've seen before include "Ray of light; treat unfairly" , "Body of an arrow" , "An arrow or a mine passage" , "Ray of light; spear" , "Handle - rod - passageway" .)
