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. For instance, the sentence “It will either rain this week or it won’t rain this week,” is tautology. The word tautology comes from the Greek word tautologia, which means repeating that which has been said.
