Could be adoring a description of classical knot (7)
I believe the answer is:
gordian
'knot' is the definition.
(Gordian knot is an example)
'could be adoring' is the wordplay.
'could be' is an anagram indicator.
'adoring' with letters rearranged gives 'GORDIAN'.
'a description of classical' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for gordian that I've seen before include "Cut the . . . . . . . knot to solve a problem by unexpected means" , "Knot only loosed by Alexander the Great with a sword" , "To cut the - knot is to solve a hard problem" , "The - - knot (mythology)" , "Cut the ....... knot ot solve problem forcefully" .)
