Avarice
Etymology
From Latin avaritia, "greed," from avarus, "greedy," which derives from avere, "to crave, to long for." One of the traditional seven deadly sins, avarice is the craving turned specifically toward wealth. The Latin sense of insatiable longing survives intact in the modern word.
noun · /AV-uh-ris/
Extreme greed for wealth, especially an obsessive desire to accumulate and hoard money.
What it names
The vice of loving money for its own sake — the grasping, hoarding hunger that treats getting more as an end in itself.
Example
It was not need but sheer avarice that drove him to underpay the very workers who had made him rich.
Related idea
Greed is the wider hunger for more of anything — food, power, attention. Avarice is greed with a single object: money, and the keeping of it.
