Tautology means to state an idea, then state the idea again using different words such as stating, “The autobiography I read was about the author’s life.” Tautology also describes a phrase or idiom in which the same idea is expressed twice using different words, such as the idiom jot or tittle. In terms of logic, tautology is a statement that is composed of two facts, one of which must be true in all possible interpretations or situations.
