What is a demonym?
A “demonym” is a noun for the people from or living in a specific place (e.g., “New Yorker,” “Japanese,” and “Puerto Rican”).
Demonyms often double as proper adjectives (e.g., “French bread”). Demonyms and their related adjectives aren’t always the same, though. For example, the demonym for Denmark is “Dane,” but the proper adjective is “Danish.”
