Have you ever used an aneroid barometer before?

No, I haven't. How does it work?

It's pretty cool since it doesn't use any liquid, just air pressure.

That sounds interesting! I should try one sometime.

Root Explanation

Aneroid → It is formed from "an-" (meaning without) and "eroid" (from Greek "eidos", meaning form or shape). The word "aneroid" refers to a device that operates without liquid, thus lacking the typical form associated with liquid-filled instruments.

Memory Tip

Think of 'without' ('an-') and 'form' ('eroid') to remember that an aneroid is a device that functions without liquid.
