History and etymology of axiom

The noun 'axiom' traces its roots to ancient Greece, particularly to the philosopher Euclid's work in geometry. The term has its origins in the Greek word 'axios,' meaning 'worthy' or 'deserving.' Etymologically, an 'axiom' is something that is deemed worthy or deserving of acceptance without further proof because it is self-evident or universally recognized as true. This notion of inherent worthiness and undeniable truth underlies the concept of axioms in mathematics and philosophy, where they serve as fundamental principles upon which logical reasoning and deduction are built. Thus, the etymology of 'axiom' illuminates its role as a foundational and self-evident statement or proposition.
