Ill fame I'm not sure should be raised in argument (9)
I believe the answer is:
disrepute
'ill fame' is the definition.
(I've seen this before)
'i'm not sure should be raised in argument' is the wordplay.
'i'm not sure' becomes 'er' (expression of hesitation).
'should be raised' says the letters should be written in reverse (in a down clue, letters go up).
'in' indicates putting letters inside.
'argument' becomes 'dispute' (I've seen this in another clue).
'er' back-to-front is 're'.
're' placed inside 'dispute' is 'DISREPUTE'.
(Other definitions for disrepute that I've seen before include "Ill fame" , "Ignominy" , "State of being held in low public esteem" , "get a bad name" .)
