This brief study of our own terms of relationship leads me to speak about the name by which our system is generally known. Morgan called it the “descriptive system,” and this term has been generally adopted. I believe, however, that it is wholly inappropriate. Those terms which apply to one person and to one person only may be called descriptive if you please, though even here the use does not seem very happy. When we pass beyond these, however, our terms are no whit more descriptive than those of the classificatory system. We speak of a grandfather, not of a father’s father or a mother’s father, only distinguishing grandfathers in this manner when it is necessary to supplement our customary terminology by more exact description. Similarly, we speak of a brother-in-law, and only in exceptional circumstances do we use forms of language which indicate whether reference is being made to the brother of the husband or wife or to the husband of a sister. Such occasional usages do not make our system descriptive, and if they be held to do so, the classificatory system is just as descriptive as our own. All those peoples who use the classificatory system are capable of such exact description of relationship as I have mentioned. Indeed, classificatory systems are often more descriptive than our own. In some forms of this system true descriptive terms are found in habitual use. Thus, in the coastal systems of Fiji the mother’s brother is often called _ngandina_ (_ngane_, sister of a man, and _tina_, mother), this term being used in place of the _vungo_ already mentioned. Similar uses of descriptive terms occur in other parts of Melanesia. Thus, in Santa Cruz the father’s sister is called _inwerderde_ (_inwe_, sister, and _derde_, father). This relative is one for whom Melanesian systems of relationship not infrequently possess no special designation, and the use of a descriptive term suggests a recent process which has come into action in order to denote a relative who had previously lacked any special designation. If “descriptive” is thus an inappropriate name for our own system, it will be necessary to find another, and I should like boldly to recognise the direct dependence of its characters on the institution of the family and to speak of it as the “family system.”
