A gentilic noun is a noun that describes the ethnic identity of a person or group of people.
Biblical Hebrew expresses national, tribal, or ancestral identity using nouns that (usually) immediately follow the noun they describe. For this reason, some scholars prefer to classify gentilic nouns as gentilic adjectives, because they appear in the same position as attributive adjectives. Either classification is grammatically correct.
