Male set up by antihero in fiction (6)
I believe the answer is:
gatsby
'antihero in fiction' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'male set up by' is the wordplay.
'male' becomes 'stag' (a stag is a male deer).
'set up' says the letters should be written in reverse (in a down clue, letters go up).
'stag' backwards is 'gats'.
'gats'+'by'='GATSBY'
Can you help me to learn more?
(Other definitions for gatsby that I've seen before include "Jay, in books" , "Classic novel by F Scott Fitzgerald - 'The Great . . . . . .'" , "F Scott Fitzgerald wrote 'The Great . . .'" , "Great character in Fitzgerald novel" , "Novel millionaire" .)
