negation

Negation is a logical operation that reverses the meaning of a statement. If a statement is true, its negation is false; if it's false, the negation is true. Think of it as saying "not" or "the opposite of" something. For example, if the statement is "It is raining," then its negation is "It is not raining." Negation helps clarify, question, or deny ideas, making it a fundamental concept in reasoning and language to express contradiction or denial.
