Twist that's baffling written in English (10)
I believe the answer is:
intertwine
'twist' is the definition.
(I know that intertwine is a more specific form of the action the twist)
'baffling written in english' is the wordplay.
'baffling' indicates an anagram.
'english' becomes 'E' (abbreviation).
'written' with letters rearranged gives 'intertw'.
'intertw'+'in'+'e'='INTERTWINE'
'that's' acts as a link.
(Other definitions for intertwine that I've seen before include "Weave" , "Twist together" , "Lace" , "Wire intent (anag)" .)
