Besotted with Gordian knot (7)
I believe the answer is:
adoring
'besotted' is the definition.
'gordian knot' is the wordplay.
'knot' indicates anagramming the letters (I've seen 'knotted' mean this).
'gordian' is an anagram of 'ADORING'.
'with' is the link.
(Other definitions for adoring that I've seen before include "Greatly loving" , "Very keen on" , "Worshipping; admiring" , "Really getting into" , "Worshipping the loved one" .)
