Tautology / noun / tau·tol·o·gy

The word tautology is a noun that refers to the concept of unnecessary or unintentional repetition in the written or spoken word. Often these words, phrases, or ideas that are repeated are considered “wordy” and considered a stylistic fault.

An example of tautology would be the use of the phrase “always and forever.” Both these words have the same meaning, and the use of them together is unnecessary.

Additionally, tautology can also refer to logical statements that are true by virtue or necessity.

The word "tautology" comes from the ancient Latin and Greek word "tautologia," which means "the saying of the same thing twice."

Using tautology in English can be traced back as far as the 13th century. The word "tautologous" meant "containing the same meaning as the word preceding it." Tautology became popular around 1566.
