Energy for every condiment (6)
I believe the answer is:
pepper
'condiment' is the definition.
(I know that pepper is a type of spice)
'energy for every' is the wordplay.
'energy' becomes 'pep' (personal energy, vim).
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'pep'+'per'='PEPPER'
(Other definitions for pepper that I've seen before include "Condiment or vegetable" , "Dot" , "Spicy condiment" , "it may be black or white" , "Hot-tasting spice" .)
