from αξίωμα first used in the sense axiom by Aristotélis so it has traditions
Yes like troll says αξίωμα means office (high), dignity. In philosophy and mathematics it still has the original meaning of Aristotelis: axiom (basic principle for a theory, unproven, if you accept the axioms of a theory you have accepted the whole theory)
Is it police officer or a militar range? Mm... searching in the internet, it seems the military range.
