According to Merriam-Webster, the term "crazy" was first used as an adjective in 1566. In 1842, Charles Dickens used the word to describe a plantation he visited in "American Notes", describing the scene:
All I saw of them, was, that they were very crazy, wretched cabins, near to which groups of half-naked children basked in the sun, or wallowed on the dusty ground.
According to The/Thirty, the term "crazy" was not used in a positive way until the 1920s:
when jazz culture reappropriated the word to mean "cool, exciting" in a slang context.
Today, many professionals and people with mental health conditions feel that the word “crazy” is very stigmatizing and demeaning to people with such conditions.
