Meaning & History
Derived from Greek ἄρειος (areios) meaning "of Ares" or "devoted to Ares." This word has also been explained as meaning "warlike, martial", which is understandable, given that Ares is the Greek god of war. Also compare the Greek words ἀρειά (areia) "threats, menaces" and ἀρειή (areiē) "cursing, threatening", which look like they are etymologically related.
