Loves an anagram to unravel (5)
I believe the answer is:
solve
'unravel' is the definition.
(I've seen this before)
'loves an anagram' is the wordplay.
'an anagram' indicates anagramming the letters.
'loves' is an anagram of 'SOLVE'.
'to' is the link.
(Other definitions for solve that I've seen before include "Work out (a problem)" , "Complete crossword" , "Unravel (a problem)" , "Unscramble" , "Find the key - work out" .)
