What term means to say the opposite of?

The term that means to say the opposite of is "contradict." This word is derived from the Latin roots "contra," meaning "against," and "dict," meaning "to say." When someone contradicts another person's statement, they provide an opposing viewpoint or assertion, effectively negating or disputing the original claim. This ability to express an opposing idea or sentiment is essential in discussions, debates, and analytical writing, where understanding multiple perspectives is crucial.

The other choices do not convey this meaning. "Attribute" refers to assigning a quality or characteristic to someone or something, rather than expressing an opposite. "Impose" means to force something upon someone, which does not relate to stating the opposite of something. "Transition," on the other hand, indicates a change from one state to another, not an expression of opposition.
