What Is The Difference Between Tautology And Redundancy? Tautology is redundancies within phrases. Redundancy is any kind of repetition: phrases, sentences, paragraphs, entire books, it’s all the same; the scale isn’t important. A tautology refers to phrasing that repeats a single meaning in identical words: They followed each other one after the other in succession.
