While anthropologists agree on some traditional major subgrouping of Apaches, they have often used different criteria to name finer divisions, and these do not always match modern Apache groupings. Some scholars do not consider groups residing in what is now Mexico to be Apache. In addition, an Apache individual has different ways of identification with a group, such as a or clan, as well as the larger tribe or language grouping, which can add to the difficulties in an outsider comprehending the distinctions.
