Board game Manet invented featuring Newton (10)
I believe the answer is:
management
'board' is the definition.
(I've seen this before)
'game manet invented featuring newton' is the wordplay.
'invented' indicates anagramming the letters.
'featuring' means one lot of letters goes inside another.
'newton' becomes 'N' (symbol for the scientific unit of force).
'game'+'manet'='gamemanet'
'gamemanet' is an anagram of 'maagement'.
'maagement' enclosing 'n' is 'MANAGEMENT'.
(Other definitions for management that I've seen before include "The bosses" , "Organisation heads" , "Senior staff" , "Organisation's leaders" , "Person employed to improve organisational efficiency" .)
