This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

These families are not listed in Glottolog, despite more than one of their branches being listed, and are therefore implicitly rejected. This category is called by setting glotto to "none" in {{ Infobox language family}}.

Family articles were checked against Glottolog 2.2, and may need updating.
