Overview
The Border or Upper Tami languages are an independent family of Papuan languages in Malcolm Ross's version of the Trans–New Guinea proposal.
Unlike the neighboring Sepik languages and many other Papuan language families of northern New Guinea, Border languages do not have grammatical gender or number (dual and plural forms).
Name
The Border family is named after the Indonesia – Papua New Guinea border, which it spans. Other than the Border languages, the Skou, Senagi, Pauwasi, Anim, and Yam families also span the Indonesia – Papua New Guinea border.
Classification history
Cowan (1957) tentatively proposed a "Tami" family, named after the Tami River, that included the modern Border and Sko language families. Some of the previously unclassified languages did turn out to be Sko, and were added to that family; the remainder (including the languages of the upper Tami) constitute the Border family.
