Further, when the name of the deceased happens to be that of some common object, such as an animal, or plant, or fire, or water, it is sometimes considered necessary to drop that word in ordinary speech and replace it by another. A custom of this sort, it is plain, may easily be a potent agent of change in language; for where it prevails to any considerable extent many words must constantly become obsolete and new ones spring up. And this tendency has been remarked by observers who have recorded the custom in Australia, America, and elsewhere. For example, with regard to the Australian aborigines it has been noted that the dialects change with almost every tribe. Some tribes name their children after natural objects; and when the person so named dies, the word is never again mentioned; another word has therefore to be invented for the object after which the child was called. The writer gives as an instance the case of a man whose name Karla signified fire; when Karla died, a new word for fire had to be introduced. Hence, adds the writer, the language is always changing. Again, in the Encounter Bay tribe of South Australia, if a man of the name of Ngnke, which means water, were to die, the whole tribe would be obliged to use some other word to express water for a considerable time after his decease. The writer who records this custom surmises that it may explain the presence of a number of synonyms in the language of the tribe. This conjecture is confirmed by what we know of some Victorian tribes whose speech comprised a regular set of synonyms to be used instead of the common terms by all members of a tribe in times of mourning. For instance, if a man called Waa ( crow) departed this life, during the period of mourning for him nobody might call a crow a waa; everybody had to speak of the bird as a narrapart. When a person who rejoiced in the title of Ringtail Opossum (weearn) had gone the way of all flesh, his sorrowing relations and the tribe at large were bound for a time to refer to ringtail opossums by the more sonorous name of manuungkuurt. If the community were plunged in grief for the loss of a respected female who bore the honourable name of Turkey Bustard, the proper name for turkey bustards, which was barrim barrim, went out, and tillit tilliitsh came in. And so mutatis mutandis with the names of Black Cockatoo, Grey Duck, Gigantic Crane, Kangaroo, Eagle, Dingo, and the rest.
A similar custom used to be constantly transforming the language of the Abipones of Paraguay, amongst whom, however, a word once abolished seems never to have been revived. New words, says the missionary Dobrizhoffer, sprang up every year like mushrooms in a night, because all words that resembled the names of the dead were abolished by proclamation and others coined in their place. The mint of words was in the hands of the old women of the tribe, and whatever term they stamped with their approval and put in circulation was immediately accepted without a murmur by high and low alike, and spread like wildfire through every camp and settlement of the tribe. You would be astonished, says the same missionary, to see how meekly the whole nation acquiesces in the decision of a withered old hag, and how completely the old familiar words fall instantly out of use and are never repeated either through force of habit or forgetfulness. In the seven years that Dobrizhoffer spent among these Indians the native word for jaguar was changed thrice, and the words for crocodile, thorn, and the slaughter of cattle underwent similar though less varied vicissitudes. As a result of this habit, the vocabularies of the missionaries teemed with erasures, old words having constantly to be struck out as obsolete and new ones inserted in their place. In many tribes of British New Guinea the names of persons are also the names of common things.
The people believe that if the name of a deceased person is pronounced, his spirit will return, and as they have no wish to see it back among them the mention of his name is tabooed and a new word is created to take its place, whenever the name happens to be a common term of the language. Consequently many words are permanently lost or revived with modified or new meanings. In the Nicobar Islands a similar practice has similarly affected the speech of the natives. A most singular custom, says Mr. de Roepstorff, prevails among them which one would suppose must most effectually hinder the 'making of history,' or, at any rate, the transmission of historical narrative. By a strict rule, which has all the sanction of Nicobar superstition, no man's name may be mentioned after his death! To such a length is this carried that when, as very frequently happens, the man rejoiced in the name of 'Fowl,' 'Hat', 'Fire,' 'Road,' etc., in its Nicobarese equivalent, the use of these words is carefully eschewed for the future, not only as being the personal designation of the deceased, but even as the names of the common things they represent; the words die out of the language, and either new vocables are coined to express the thing intended, or a substitute for the disused word is found in other Nicobarese dialects or in some foreign tongue. This extraordinary custom not only adds an element of instability to the language, but destroys the continuity of political life, and renders the record of past events precarious and vague, if not impossible.
