exhumed

I'm a little stuck... Click here to teach me more about this clue!

'dug up' is the definition.
(exhuming is a kind of digging up)

'old stink journalist' is the wordplay.
'old' becomes 'ex'.
'stink' becomes 'hum' (I can't explain this - if you can you should believe this answer much more).
'journalist' becomes 'ed' (short for editor).
'ex'+'hum'+'ed'='EXHUMED'

Can you help me to learn more?

(Other definitions for exhumed that I've seen before include "Disinterred" , "Dug out (a corpse)" , "Disintered" , "Dug up a dead body" , "brought to surface" .)

I've seen this clue in The Guardian.
