Etymology

Origin of amplify

First recorded in 1375–1425; late Middle English amplifyen, from Middle French amplifier, from Latin amplificāre “to increase, augment”; equivalent to ample + -ify

Explanation

The verb amplify means to crank up the volume. Speakers amplify, or raise, the volume of the noise coming through a microphone so that everyone at the rock show can hear. Amplify comes from the Old French word amplifier meaning "to enlarge or expand." It refers to making a sound “expand,” but it can also crank up something like a disagreement — if you spread rumors, you might amplify an argument. It can “enlarge” an idea — if you don't realize how bad your health is, your doctor might amplify your test results by explaining them to you in simple, and possibly frightening terms.
