Abundance, profusion (6)
I believe the answer is:
wealth
I believe this clue is a double definition.
'abundance' is the first definition.
(I know that wealth is a type of abundance)
'profusion' is the second definition.
(wealth is a kind of profusion)
(Other definitions for wealth that I've seen before include "An abundance of valuable possessions or money" , "Abundance of resources" , "Mammon" , "Assets" , "Possessions and resources" .)
