Cut up some meat (4)
I believe the answer is:
chop
I believe this clue is a double definition.
'cut up' is the first definition.
(I've seen this in another clue)
'meat' is the second definition.
(chop is a kind of meat)
'some' acts as a link.
(Other definitions for chop that I've seen before include "Dissect" , "Cut by blow of axe" , "Piece of meat - the sack" , "mutton slice" , "Cutlet" .)
