Etymology

Origin of superstition

First recorded in 1375–1425; late Middle English, from Latin superstitiōn-, stem of superstitiō, from superstit-, stem of superstes “standing beyond, outliving” (from super- super- + -stes, combining form of stāre “to stand”) + -iō -ion

Explanation

A superstition is a belief or practice that isn’t entirely based on facts or reality, like carrying a rabbit’s foot because you think it brings you good fortune, or believing that Friday the 13th is a day of bad luck. When you pick up a penny, is it because you’re poor or do you think it’s lucky? If the quickest route makes you walk under a ladder, will you do it even though it’s bad luck? These are two examples of superstitions, irrational decisions we make for some weird reason. The Latin roots of the word translate as “standing over,” like how you freeze standing over a broken mirror. Don’t worry, it’s only a superstition, right?
