Novelist sounds more correct (6)
I believe the answer is:
writer
'novelist' is the definition.
(I've seen this before)
'sounds more correct' is the wordplay.
'sounds' shows a homophone (sound like).
'more correct' becomes 'righter' ('right' can be a synonym of 'correct').
'righter' is a homophone of 'WRITER'.
(Other definitions for writer that I've seen before include "Author; correspondent" , "Memorandum could one produce?" , "Novelist" , "Quiller" , "Scribe, author" .)
