Etymology
Origin of defiance
First recorded in 1250–1300; Middle English, from Old French; equivalent to defy + -ance
Explanation
Stand up when the powers that be order you to sit down, and you've given a fine example of defiance. It happens when someone or a group of someones openly flouts or challenges authority. Refusing to go to bed when your parents tell you to? That's an act of defiance. Defiance comes from French — specifically to the Old French word defier, which means "to defy." (Don't mix it up with deify; that means to make someone or something into a god.) If you've ever studied Latin, you'll spot the fi in fidare, "to trust."
