Fun Fact
While it sounds academic, tautological shows up all over everyday conversation—and advertising. “Added bonus,” “final conclusion,” “completely unanimous”—all examples of tautologies, or statements that repeat themselves. In formal logic, a tautology is always true (like “it will rain or it won’t”), but in writing and speech, it’s often just a filler phrase that adds no substance. Editors, professors, and debate judges hate it because it pretends to sound smart while saying absolutely nothing new.
(adjective) Completely airtight and sealed; or, completely closed off from outside influence or interference.
