Dig up old philosopher (6)

I believe the answer is:

exhume

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

'old philosopher' is the wordplay.
'old' becomes 'ex'.
'philosopher' becomes 'hume' (I've seen this in other clues).
'ex'+'hume'='EXHUME'

(Other definitions for exhume that I've seen before include "Dig up (a corpse)" , "Disinter a dead body" , "Reveal" , "Dig up, unearth" , "opposite of 5 [ENTOMB]" .)

I've seen this clue in The Times and The Guardian.
