Wine list, initiallly, that is right for king's supporter (8)
I believe the answer is:
cavalier
'supporter' is the definition.
(Cavalier is an example)
'wine list initiallly that is right for king's' is the wordplay.
I cannot quite understand how this works, but
'wine' could be 'cava' (type of Spanish wine) and 'cava' is located in the answer.
'right' could be 'r' (abbreviation) and 'r' is found within the answer.
'that is' could be 'ie' (short for Latin 'id est', 'that is') and 'ie' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cavalier that I've seen before include "Horseman" , "Showing a lack of proper concern" , "... King Charles, canine breed" , "Knight" , "Casual" .)
