Twist, warp (7)
I believe the answer is:
distort
I believe this clue is a double definition.
'twist' is the first definition.
(I know that twist can be written as distort)
'warp' is the second definition.
(I know that warp can be written as distort)
(Other definitions for distort that I've seen before include "turn crooked" , "Pervert" , "Twist out of shape" , "Get out of shape" , "Deform" .)
