Olympian

From Late Middle English Olympyan, from Latin Olympius (“of or relating to Mount Olympus”) and its etymon Ancient Greek Ὀλῠ́μπῐος (Olŭ́mpĭos, “of or relating to Mount Olympus; living on Mount Olympus; Olympian”) + English -an (suffix forming adjectives meaning ‘of or pertaining to’, or forming agent nouns). Ὀλῠ́μπῐος (Olŭ́mpĭos) is derived from Ὄλῠμπος (Ólŭmpos, “Mount Olympus”) (from Pre-Greek) + -ῐος (-ĭos, suffix forming adjectives meaning ‘of or pertaining to’).

From Late Latin Olympianus (“Olympic”) + English -an (suffix forming adjectives meaning ‘of or pertaining to’, or forming agent nouns). Olympianus is derived from Latin Olympia (“town in Elis, Greece, where the ancient Olympic Games were held”) + -ānus (suffix meaning ‘of or pertaining to’); and Olympia is from Ancient Greek Ὀλυμπῐ́ᾱ (Olumpĭ́ā, “Olympia”), from Ὀλῠ́μπῐος (Olŭ́mpĭos, “of or pertaining to Mount Olympus; living on Mount Olympus, Olympian; (specifically) Zeus”) or Ὄλῠμπος (Ólŭmpos, “Mount Olympus”) (see further at etymology 1) + -ῐ́ᾱ (-ĭ́ā, suffix forming feminine abstract nouns).
