Origin
- Proto-Indo-European*h₁ep-
- Proto-Indo-European*h₁éps
- Proto-Indo-European*h₁épi
- Proto-Hellenic*epí
- Ancient Greekἐπί (epí)
- Ancient Greekὄνυμα (ónuma)
- Ancient Greekἐπώνυμος (epṓnumos)
- Latinepōnymu
- Frenchéponyme
- Englisheponym
Borrowed from French éponyme (“eponymous person”), from the nominalization of the adjective éponyme (“eponymous”), from Latin epōnymus (adjective), from Ancient Greek ἐπώνῠμος (epṓnŭmos, adjective), from ἐπί (epí, “upon, epi-”) + ὄνυμα (ónuma, “name”) + -ος (-os, suffix forming compound adjectives (often nominalizable)). By surface analysis, epi- + -onym.
