Leander certainly wasn't this central character (8)
I believe the answer is:
antihero
This clue might be a double definition.
'leander certainly wasn't this central' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'character' is the second definition.
(I know that antihero is a type of character)
Can you help me to learn more?
(Other definitions for antihero that I've seen before include "principal character lacking noble qualities" , "Protagonist without admirable qualities" , "Winston Smith in Orwell's 1984, for example" , "Central character lacking traditional courageous attributes" , "Principal character without virtue" .)
