Eccentric, holding keys, corrupt and lying (9)
I believe the answer is:
recumbent
'lying' is the definition.
(I've seen this before)
'eccentric holding keys corrupt' is the wordplay.
I cannot really see how this works, but
'corrupt' could be 'bent' (I've seen this before) and 'bent' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for recumbent that I've seen before include "flat?" , "Lying down comfortably" .)
