The word axiomatic is an adjective that refers to something that is self-evident or universally accepted as true without the need for proof or demonstration. It originates from the word axiom, which in philosophy and mathematics refers to a statement or principle that is universally recognized as being true and serves as a foundation for further reasoning or argument. An axiomatic statement is one that is so obvious or fundamental that it doesn't require further validation—it's taken as a given, often because it is universally understood or logically necessary.

In everyday usage, axiomatic is often used to describe ideas, principles, or beliefs that are widely accepted and considered unquestionable within a particular context. For example, "It is axiomatic that the sun rises in the east" or "It's axiomatic that honesty is important." In these cases, the truth of the statement is so fundamental that it doesn't need to be argued. The term is especially relevant in fields like philosophy, logic, mathematics, and law, where foundational principles serve as the basis for reasoning and further exploration.
