An Etymological Dictionary of Astronomy and Astrophysics

In any system of mathematics or logic, a statement or proposition from which secondary statements or propositions are derived. The truth of an axiom is either taken for granted or assumed. Axioms serve as the starting point of other mathematical statements called → theorems. In modern practice, axiom and → postulate have the same meaning.

Etymology (EN): M.Fr. axiome, from L. axioma, from Gk. axioma “authority,” literally “something worthy,” from axioun “to think worthy,” from axios “worthy,” from PIE adj. *ag-ty-o- “weighty,” from base *ag- “to drive, draw, move.”

Etymology (PE): Bondâšt, literally “taking as the base,” from bon “root, origin, base” + dâšt “held,” from dâštan “to have, to hold, to maintain, to consider.”
Arzâqâzé, from arz “value” + âqâzé “beginning, principle,” from âqâz “beginning.”
