Apron

Back in the Middle Ages, the French called this protective cooking gear a naperon. But once English speakers adopted the word, the phrase “a napron” often blended together when people said it out loud. As a result, “a napron” became “an apron,” instead—and we have spelled it that way ever since. Check out more accidental discoveries that changed the world.

Algorithm

The original Medieval Latin version of this word, algorismus, was named after a famous Arab mathematician. But the term is actually just a bad translation of his last name, al-Khwarizmi. Don’t miss these common words that used to mean completely different things.

Sneeze

Believe it or not, sneeze was originally spelled with an F, not an S—as in fneze. Why the change? According to one explanation, people often misread the lowercase f as the old-fashioned long S character, ſ. Eventually, the spelling error simply became the norm.

Squeeze

In Old English, the term quease meant to press or crush firmly. The extra “s” was mistakenly added later on, probably due to the word’s likeness to other expressions that begin with “squ-,” like squash and squat. You’ll never believe these silly-sounding words are real—but they are.

Pea

One pea was originally called a pease in Middle English. However, it was often misinterpreted as a plural word, thanks to the last "s" sound. This led scholars to create a singular version of the word, pea, in the 17th century. According to Mental Floss, the actual plural of pease in Middle English was pesen.

Nickname

A secondary or unofficial name in the late Middle Ages was an ekename—which literally meant “also-name.” Frequent references to “an ekename” eventually turned into "a nickname."

Sashay

Although the English borrowed the French word chasse—a verb that means "to chase"—to describe a "gliding step," they butchered the pronunciation by swapping the "sh" and "s" sounds.

Ammunition

Like “nickname” and “apron,” ammunition was born from an incorrect division. French soldiers in the Middle Ages misheard the French word “la munition” as l'amonition, and the English language later adopted this misspelling in the 17th century. On the other hand, these words mean the exact opposite of what you think.

Umpire

This word came from the French term “nompere,” or “one without equal.” But because the sounds blurred together when spoken out loud, “a noumpere” ended up becoming “an oumpere,” later forming the word we now know as umpire.
