Twist in wet coils (5)
I believe the answer is:
twine
'twist' is the definition.
(I know that twist can be written as twine)
'in wet coils' is the wordplay.
'coils' is an anagram indicator (I've seen this in other clues).
'in'+'wet'='inwet'
'inwet' is an anagram of 'TWINE'.
(Other definitions for twine that I've seen before include "Strong thread or string" , "Interweave" , "Garden string" , "Coil" , "Knot" .)
