Dogsbody’s deed interrupting turning up of corporation (8)
I believe the answer is:
factotum
'dogsbody's' is the definition.
(I've seen this before)
'deed interrupting turning up of corporation' is the wordplay.
'deed' becomes 'act' (an action).
'interrupting' indicates putting letters inside.
'turning up' says the letters should be written backwards.
'corporation' becomes 'tum' ('corporation' can humorously mean belly fat).
'of' reversed gives 'fo'.
'act' placed into 'fo' is 'facto'.
'facto'+'tum'='FACTOTUM'
(Other definitions for factotum that I've seen before include "Dogsbody" , "One who does all kinds of work" , "'Retainer, servant (8)'" , "Man Friday" , "Jack of all Trades" .)
