Butchers in group combined talents (5,3)
I believe the answer is:
skill set
'butchers' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'in group combined talents' is the wordplay.
'in' means one lot of letters goes inside another.
'group' becomes 'set' (set is a kind of group).
'combined talents' becomes 'kills' (I can't explain this - if you can you should give a lot more credence to this answer).
'set' placed around 'kills' is 'SKILL SET'.
Can you help me to learn more?
(Another definition for skill set that I've seen is " capabilities".)
