Stuff concluded each time (7)
I believe the answer is:
overeat
'stuff' is the definition.
(synonyms)
'concluded each time' is the wordplay.
'concluded' becomes 'over' (synonyms).
'each' becomes 'ea'.
'time' becomes 't' (abbreviation).
'over'+'ea'+'t'='OVEREAT'
(Other definitions for overeat that I've seen before include "Be gluttonous" , "Indulge in gluttony" , "ignore threat of a big corporation?" , "Gorge oneself" , "pig out?" .)
