Tautology is a way to express something by repeating or saying it in a different way. This can be used for emphasis, to convey something important, or to add literary beauty to a text. However, many times its use is inadvertent and is just a needless repetition. In logic, it is a statement that consists of two facts, one which will be true in any instance.
