Bit of rump or knuckle: dinner for the carnivore? (4)
I believe the answer is:
pork
'dinner for the carnivore?' is the definition.
(pork is a type of meat)
'bit of rump or knuckle' is the wordplay.
'bit of' indicates a hidden word.
'PORK' is hidden within 'rump or knuckle'.
(Other definitions for pork that I've seen before include "Meat used in sausages" , "Cassoulet ingredient" , "Bacon, e.g." , "Pig's flesh as food" , "Food -- hats -- falsehoods" .)
