What does eponymy mean?
Eponymy is the practice of naming people, places, things, works, or events after other people. It describes both the convention itself and the names that result from it. The practice is especially visible in medicine, science, geography, literature, and the arts, where discoveries, diseases, streets, buildings, and cultural periods may carry the name of an earlier individual. Eponymy can honor a person and preserve historical memory, but it can also raise questions about whose achievements are remembered and whose are overlooked. The related word eponym refers to the person after whom something is named, while eponymous describes a name or thing formed in this way. Eponymy is a useful term for discussing how personal names become part of shared cultural and scientific vocabulary.

Where does eponymy come from?
Eponymy entered English in the 17th century through New Latin eponymia, from Greek eponymia, a word associated with eponymos, “one who gives a name” or “a name-giver.” Its Greek elements combine epi-, meaning “upon” or “after,” with onoma, meaning “name.” The word shares that name-forming root with terms such as anonymous, autonym, and synonym, while its direct English derivatives include eponym, eponymous, and eponymously.
