Definition & pronunciation of <b>crazy</b>

Where does the word crazy come from?

The word "crazy" has a fascinating etymology. It originated in the 14th century from the Old French word "crever," which means "to break" or "to crack." Initially, "crazy" referred to an object that was broken or fractured, such as a cracked pot. Over time, the meaning shifted to describe someone whose mind was "broken" or "unstable." In the 16th century, the term "crazy" was used to describe someone who was wild, mad, or eccentric. In the 19th century, the phrase "go crazy" emerged, meaning to act wildly or erratically. Today, "crazy" is used to describe a wide range of behaviors, from mild eccentricity to severe mental illness. Despite its complex history, the word "crazy" remains a versatile and widely used term in modern language.
