Usage

What does rebellious mean? Rebellious is an adjective that describes someone who resists or defies rules. Someone who acts in such a way can be called a rebel. However, the word rebel can also be used to refer to a revolutionary trying to overthrow a government. Such actions can be described as rebellious, but rebellious is much more commonly used to describe people or actions that break the rules, resist authority, or otherwise challenge the status quo. It’s especially applied to teenagers who act this way. The noun rebelliousness refers to such behavior. The noun rebellion can refer to this, but it’s also used to refer to an attempt to overthrow a government (rebelliousness isn’t typically used this way.)Example: Danielle was labeled rebellious for refusing to wear her uniform to school.
