Question

What Are Tautologies?

Answer 1

Answer:In logic, a tautology is a formula or assertion that is true in every possible interpretation. A simple example is " or". Philosopher Ludwig Wittgenstein first applied the term to redundancies of propositional logic in 1921.

Answer 2

Tautology is useless restatement, or saying the same thing twice using different words. “Speedy sprint" is a tautology because sprint already means "speedy running." The noun tautology originates from the Greek word tautologos, meaning “repeating what is said.”
