This paper has two purposes: first, to present the facts of the system
of kinship terminology of Angas; and second, to propose a formalism for
representing such facts within linguistic descriptions. The analysis
presented is purely formal, with no discussion of the cultural or func
tional expression of the system in behavior. A number of anthropological
concepts are found to be useful in the description; of particular note
are the principle of reciprocity, and the necessity of carrying out
kinship investigations from the point of view of both male and female
Ego. It is argued that the proposed formalism is superior to other such
systems which have been proposed because of its capacity for ready in
tegration into current linguistic theory because of format and rule
type. A few concluding remarks are made regarding suggested application
of the proposed formalism to matters of semantic change and
reconstruction.
