Origin of rapid

First recorded in 1625–35, rapid is from the Latin word rapidus “tearing away, seizing, swift”; see rape 1, -id 4

Explanation

Rapid means happening with great speed or in a brief period of time. Think of Rapid Eye Movement (REM sleep), when your eyes are darting back and forth quickly — trying to follow your fast-paced dreams. Rapid comes from the Latin word rapere, which means "to hurry away" or "to seize."
