Other forms: pumps; pumping; pumped

A pump is a machine that sucks up liquid from one place and moves it somewhere else, like a gas pump. If you’re pumped about this word, you can put on pumps, pump up the volume, and pump some iron!

When you use the device called a pump, you pump water or gas. Other things that force some liquid or gas to move, also pump: your heart pumps blood, and your foot pumps the brake of your car when you're stopping on an icy road. If you pump iron, you lift weights. If you’re pumped, you’re excited. “Pump Up the Volume” was a hit song in 1987, so turn it up. A pump is also a woman's dress shoe.
