Forms

ἐπώνῠμος (epṓnumos) m or f (neuter ἐπώνῠμον); second declension[1]

Etymology

It is formed from Ancient Greek ἐπί (epí, “upon”) + ὄνυμα (ónuma, “name”), with the Aeolic and Doric form of ὄνομα (ónoma).[1][2][3] The ⟨ο⟩ of the name is lengthened to ⟨ω⟩ in the compound, as in ἀνώνυμος (anṓnumos, “nameless”) and ὁμώνυμος (homṓnumos, “having the same name”).[4][3]

Earliest recorded meaning

In Homer it is said of a name given for a reason: Alcyone was named so because of her mother's grief, and Odysseus's name recalls his grandfather's anger.[2][4] Arete's name, “the Prayed-for”, is called epōnumon in the Odyssey without a reason being given.[4][2]

Semantic evolution

Hesiod uses it the same way of the Cyclopes.[4][5] In tragedy a god or person is epōnumos when true to their name, as Aeschylus says of Hermes the escort and Euripides of Polynices.[4][5] From Pindar and Herodotus on it means “named after” someone or something, and Herodotus also uses it for a further name, a surname.[4][5] Sophocles, Euripides and the orators use it of the one who gives a name to a land or people.[5] At Athens the eponymous heroes gave their names to the ten tribes and to the year-groups of men liable for service; official notices were posted at their statues in the agora.[5]

Modern Greek επώνυμος (epónymos) is the ancient word revived, and its neuter επώνυμο (epónymo) is the word for a surname.[6][3] English eponym (1833) comes from the Greek word.[7]
