axiom A statement that is considered to be true without need of proof. The term "axiom" comes from the Greek axios meaning "worthy" and was used by many Greek philosophers and mathematicians, including Aristotle. Curiously, Euclid, whose axioms are best known of all, seems to have favored a more general phrase meaning "common notion."
