Archetypical (7)
I believe the answer is:
classic
'archetypical' is the definition.
(thesaurus)
This is the entire clue.
(Other definitions for classic that I've seen before include "Eg, screw thread" , "Major long-standing sporting event" , "Very great work of art" , "Timeless-quality work; a race" , "Recognised as the best" .)
