Definition

1. Adjective:
   • Characterized by unnecessary repetition of meaning using different words: Describes a statement, phrase, or argument that says the same thing twice in slightly different words, making it redundant. It often involves using synonyms or near-synonyms together, adding no new information.

Usage

• The term "tautological" is used to critique or identify redundancy in language, logic, or argumentation. It is a formal adjective, commonly applied in academic, linguistic, or logical contexts to point out that an expression is needlessly repetitive.
• Example: Calling the statement "a round circle" tautological because "round" is inherent in the definition of a "circle."

Examples

• Adjective:
  • The phrase "an unexpected surprise" is considered tautological because a surprise is, by definition, unexpected.
  • His argument became tautological when he defined "freedom" as "the state of being free."
  • The editor removed the tautological expression "close proximity" from the report.

Advanced Usage

• In Logic and Philosophy: A tautological statement is one that is true in every possible interpretation or by its logical form alone, such as "All bachelors are unmarried men." In this stricter sense, it is necessarily true but uninformative.
  • The proposition "Either it will rain, or it will not rain" is logically tautological.
• As a Rhetorical Device: Sometimes used intentionally for emphasis, though it is generally discouraged in precise writing.
