Note 32 — INTRODUCTION
Reading edition
Even more than their customs the social constitution of several Naga tribes suggests a diversity of origin. In more than one tribe we find traces of a dual division crossed by a triple one, and indicating a division into three elements, either as three separate groups or as two primary groups, one of which is again split making three. In addition to these there are odd clans descended from “men caught in the jungle” and others, as already mentioned. Thus among the Aos are found two linguistic groups, Chongli and Mongsen, existing side by side in the same villages though retaining frequently their different languages, and always, among the women, their differences of tattoo and of hairdressing. The word for “mother” in the one of these two Ao languages is ocha (Chongli), in the other avu (Mongsen). Across this dual division of the Aos we get a triple division into three clans, Pongen, Langkam and Chami, which are nominally at any rate exogamous and which run through both the linguistic groups, though the nomenclature varies, and though the whole exogamous system is somewhat complicated by subdivision and by adoption from one group to another. Of the three groups mentioned Pongen is generally recognized as doyen, while the social position of Chami is usually regarded as decidedly inferior to the other two. Again, among the Southern Konyak villages at any rate there seem to be two linguistic and tattoo groups (one of which tattoos the face of the warrior and the other the chest only) called Thendu and Thenkoh, while there are said to be also three social divisions running through both groups, of which the first, called Ang,32 corresponds to the Ao “Pongen” and provides hereditary chiefs in those villages which possess them, though in the case of the Konyak chief the heir to the chieftainship has to be of Ang blood by both parents, contrary to the prevailing exogamous system. In the Rengma tribe we have again two linguistic groups, as among the Aos, existing side by side sometimes in the same village, and called Inseni-Kotsenu and Tseminyu respectively. Of these two groups the latter apparently are again divided into two parts distinguished by the use of different terms for “mother” (avyo and apfsü).33 The Angamis are again divided into two groups commonly known as Thevoma and Thekronoma (or Cheroma) or Solhima, using the words azo and apfu respectively for “mother,” although the former term only is in use among the numerous Chakrima sub-tribe of Angamis, though the distinction between the Thekronoma, called by them Solhima, and the Thevoma is recognized. These two divisions of the Angamis may be spoken of as Pezoma and Pepfüma respectively according to the terms they use for “mother.” The Pezoma group appears to be also subdivided into Sachema and Thevoma, two divisions of more or less equal status, though the former is actually the senior. Nowadays, however, the Sachema group, which is very small indeed numerically as compared with Thevoma, has been virtually lost sight of, and “Thevoma” includes the whole of the Pezoma. It should be added that according to tradition the Thekrono division was originally the elder, but was cheated of its birthright by the first ancestor of the Thevo division. The word Solhima, used ordinarily by a large part of the Angami tribe for the Thekronoma division, means “alien” or “stranger.”34 In the Memi group of the Angamis we have again a third division, called Cherhechima in some villages, which is regarded as socially inferior to such an extent that the other Memi will not intermarry with it. This division seems also to be regarded as the source of some unlucky emanation which has an evil influence on any who fall under it, though the neighbouring Tengima, Dzunokehena and Kezami Angamis have no objection at all to intermarrying with the Cherhechima. The Lhotas seem to be divided like the Angami into two phratries using oyo for “mother,” with a third using opfu, and, as in the case of the Angamis, the use of the distinct terms does not extend throughout the whole tribe, but seems to be dying out.35
