This article is intended not as an overview of the range of nominal classif
ication systems that can be found in the northern part of West Papua, but a
s a discussion of a typologically rare development of classification that i
s found in some languages of this quarter of New Guinea. This discursion is
set in a brief discussion of some of the more typical systems that are fou
nd in geographically, and genetically, divergent languages of the region. T
he focus of the article is the presentation of data that shows the classifi
cation of the personal pronouns into different gender classes, and examines
possible motivations for this unusual phenomenon.
