Loathed man, quiet, is seen with journalist (8)
I believe the answer is:
despised
'loathed' is the definition.
(I've seen this in another clue)
'man quiet is seen with journalist' is the wordplay.
'man' becomes 'des' ().
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'seen with' is a charade indicator (letters next to each other).
'journalist' becomes 'ed' (short for editor).
'des'+'p'+'is'+'ed'='DESPISED'
(Other definitions for despised that I've seen before include "Looked down on" , "held in contempt" , "Scorned" , "Detested" , "Had contempt or scorn for" .)
