This paper is inter-disciplinary. Its disadvantage is that the author is not sufficiently conversant with the disciplines it is inter. He may however, like Lord Wavell, claim that at least the thread that binds them is his own. The paper is of philosophic interest in that it is inspired by, and hopes to shed some light on, the notion of an ideal language. It is of interest to social anthropology in that its main subject is kinship structure. It may be of interest to mathematicians in setting a task.
