Etymology

Origin of stimulate

First recorded in 1540–50; from Latin stimulāt(us) “goaded” (past participle of stimulāre “to goad, incite,” from stimulus stimulus ( def. ) ); see -ate 1

Explanation

If the economy is starting to stall, the president can't just sit there. He has to stimulate—turn it on, bring it to life, perk it up. You can stimulate practically anything: a person, a conversation, a mind, or even the growth of a plant. Stimulate is often used to describe a physical or sexual sensation, but don't get bogged down in that kind of thinking. Often, a government will try to stimulate economic activity by creating a stimulus package. Or, say, for example, that I'm trying to sell my new song CD. In order to stimulate interest, I need to send out a sample song to all my friends. Unless, of course, my songs are no good.
