Reduces bits of meat (4)
I believe the answer is:
cuts
'reduces' is the definition.
('cut' can be a synonym of 'reduce')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cuts that I've seen before include "Tears" , "Retrenchment" , "Incisions" , "Axes" , "Snubs" .)
