Plot twist: first take what you owe (4)
I believe the answer is:
debt
'you owe' is the definition.
I can't tell whether this definition defines the answer.
'plot twist first take' is the wordplay.
'plot' becomes 'bed' (a plot of land).
'twist' is a reversal indicator (I've seen 'twisting' mean this (letters twist back)).
'first take' becomes 't' (bst letter of 'take').
'bed' reversed gives 'deb'.
'deb'+'t'='DEBT'
'what' is the link.
Can you help me to learn more?
(Other definitions for debt that I've seen before include "Money owed or due" , "state of obligation" , "Amount owed" , "Commitment" , "Amount owing" .)
