Dislike tangling thread (6)
I believe the answer is:
hatred
'dislike' is the definition.
(I've seen this before)
'tangling thread' is the wordplay.
'tangling' indicates anagramming the letters (I've seen 'tangle' mean this).
'thread' is an anagram of 'HATRED'.
(Other definitions for hatred that I've seen before include "Intense dislike" , "Great dislike" , "'Loathing, enmity (6)'" , "Extreme dislike and enmity" , "Dearth (anag)" .)
