Definition of oppositional

The word "oppositional" has its roots in the 15th century, derived from the Latin words "opponeo," meaning "to set against" or "to oppose," and the suffix "-al," indicating a relation or quality. In the 16th century, the term "oppositional" emerged to describe a person or thing that opposes or resists something else. Initially, it was used to convey a sense of conflict or adversity, such as "oppositional forces" or "oppositional attitudes." Over time, the term took on a broader meaning, encompassing not only physical opposition but also mental or psychological resistance. In the 20th century, the term "oppositional defiant disorder" was coined to describe a behavioral disorder characterized by persistent and defiant disobedience toward authority figures. Today, the word "oppositional" is used in various contexts to describe resistance, opposition, or defiance in various forms.
