“Demonym” comes from Greek — “dēmos” meaning “people,” and “onuma” meaning “name.” A demonym identifies a native of a certain geographical place or ethnic group. These words might be as simple as the name of a place with an added suffix (as in “Japanese,” “Egyptian,” and “Parisian”), or they could be entirely different words. “Mancunian,” “Neapolitan,” and “Porteño,” for example, refer to residents of Manchester, England; Naples, Italy; and Buenos Aires, Argentina, respectively.
