Etymology

Origin of dissipate

First recorded in 1525–35; from Latin dissipātus (past participle of dissipāre, dissupāre “to scatter”); see -ate 1

Explanation

To dissipate is to disperse or fade away — as a bad smell will dissipate (usually) if you wait long enough. Dissipate can also mean “spend or use wastefully.” If you win the lottery, you might suddenly find yourself with a group of new friends encouraging you to dissipate your money (on them). Note that dissipate can be used with or without an object: "Once you dissipate your wealth, your new group of friends will dissipate without a trace."
