Broken thread can be an abomination! (6)
I believe the answer is:
hatred
'an abomination' is the definition.
(thesaurus)
'broken thread' is the wordplay.
'broken' is an anagram indicator.
'thread' with letters rearranged gives 'HATRED'.
'can be' is the link.
(Other definitions for hatred that I've seen before include "Intense dislike" , "Great dislike" , "Dearth (anag)" , "Abhorrence, detestation" , "Violent emotion" .)
