Culture Name Generator

A culture name is the word a people use for themselves, or the word their neighbors use for them, and in worldbuilding it does more work than almost any other name on the map. It sets the sound of every personal name, city and kingdom that follows. Real ethnonyms tend to be short roots with a plural or adjectival ending: the root carries the flavor (Tlanexca, Qadeshim, Halgrimr) and the ending tells you how the language pluralizes (-im, -oi, -ae, -ani, -ar, -folk). Getting the root right matters more than the ending.

The names here are invented but built on recognizable phonologies so you can match a culture to its place in your world: Mesoamerican tl- and -tzin clusters for jungle city-states, guttural kh and q for steppe riders and desert traders, Norse -vik and -mark for northern seafarers, soft Polynesian vowels for island peoples, Bantu prefixes for savanna kingdoms, and broad Celtic and Slavic textures for forest and river folk. A few compound names (Tidewalkers, Mirewardens) show how a people can be named by what they do rather than what they call themselves.

Pick a name whose sound you can reuse, then derive the language, the demonym and the neighboring exonym from it.
