Untwist, unravel (11)
I believe the answer is:
disentangle
This clue is a double definition.
'untwist' is the first definition.
(I've seen this before)
'unravel' is the second definition.
(I know that unravel is a more specific form of disentangle)
(Other definitions for disentangle that I've seen before include "Decipher" , "Untwist" , "free" , "Extricate" , "Unravel" .)
