jenchaînais

Jenchaïnais is the demonym for residents of Jenchaïne, a hypothetical commune used in discussions of French toponymy and ethnonyms. The term illustrates how place names in French can yield ethnonyms for inhabitants.

Etymology and formation: Jenchaïne forms the demonym by adding the suffix -ais, a common pattern in French toponyms. The feminine form is jenchaïnaise; the masculine plural is jenchaïnais; the feminine plural is jenchaïnaises.

Usage: As a noun referring to people, the form is typically capitalized (Les Jenchaïnais). As an adjective, it agrees with the noun it modifies (for example, habitants jenchaïnais or habitantes jenchaïnaises, depending on the gender and number of the noun).

Notes: Because Jenchaïne and Jenchaïnais are fictional in this article, the discussion remains a generic illustration of demonym formation in French rather than documentation of a real community.
