Hemingway or Sterne perhaps (6)
I believe the answer is:
ernest
'hemingway' is the definition.
(author Ernest Hemingway)
'sterne perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'sterne' with letters rearranged gives 'ERNEST'.
'or' acts as a link.
(Other definitions for ernest that I've seen before include "Man's name" , "Name (of dramatic importance!)" , "A new genre is myth (anag) -- author" , "- Bevin, twentieth century Labour politician" , "Boy's name (the important one!)" .)
