This tracking category is triggered by entering "?" in the speaker field of the language infobox, but not the latest edition of Ethnologue (currently "e18") in the ref field, for boxes with ISO codes. This is done so that these articles will be flagged for attention when a new edition of Ethnologue comes out.

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.
