Panathenaea

Where it comes from

Learned borrowing from Latin Panathēnaea, and from its etymon Ancient Greek Πᾰνᾰθήναιᾰ (Pănăthḗnaiă), a noun use of the neuter plural of Παναθηναῖος (Panathēnaîos, “Panathenian”) (in Παναθήναια ἱερᾰ́ (Panathḗnaia hierắ, “Panathenian solemnities”)), from πᾰν- (păn-, prefix meaning ‘all; every’) + Ἀθηναῖος (Athēnaîos, “of or relating to Athens, Athenian”) + -ῐ́ᾱ (-ĭ́ā, suffix forming feminine abstract nouns). Ἀθηναῖος (Athēnaîos) is derived from either Ἀθῆναι (Athênai, “Athens”) or Ᾰ̓θήνη (Ăthḗnē, “Athena, patron goddess of Athens”) + -ῐος (-ĭos, suffix meaning ‘of or pertaining to’ forming adjectives).
