- Do not confuse with 'эпоним' (correct), 'тезка' (namesake, but refers to two people/things sharing a name, not the origin).
- Avoid direct calque 'eponymous hero' -> 'эпонимный герой' sounds odd; use 'заглавный герой'.
Common Mistakes
- Using 'eponym' to mean 'synonym' or 'pseudonym'.
- Confusing 'eponym' (the source person) with 'eponymous' (the thing named after).
- Pronouncing it /ˈiːpənɪm/ (it's /ˈɛpənɪm/).
