Chivalrous tale with idiosyncratic feature relating to love (8)
I believe the answer is:
romantic
'relating to love' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for romantic that I've seen before include "Relating to love" , "Soulful or amourous idealist" , "Amorous, showing loving feeling" , "Imaginative or amorous" , "Inclined to love" .)
