The quality or state of being greedy; an intense and selfish desire for wealth, food, or possessions.
From the adjective 'greedy' combined with the noun-forming suffix '-ness,' which transforms qualities into nouns to describe abstract states.
The '-ness' suffix is one of Old English's greatest gifts to word-building—it lets us turn almost any adjective into a noun, which is why 'greediness,' 'darkness,' and 'silliness' all follow the same pattern.
