Besides the sacred things, there are words and sounds which have the same character; they should not pass the lips of the profane or enter their ears. There are ritual songs which women must not hear under pain of death.[1026] They may hear the noise of the bull-roarers, but only from a distance. Every proper name is considered an essential element of the person who bears it; being closely associated in the mind to the idea of this person, it participates in the sentiments which this latter inspires. So if the one is sacred, the other is. Therefore, it may not be pronounced in the course of the profane life. Among the Warramunga there is one totem which is particularly venerated, this is the snake called Wollunqua; its name is taboo.[1027] It is the same with Baiame, Daramulun and Bunjil; the esoteric form of their name must not be revealed to the uninitiate.[1028] During mourning, the name of the dead man must not be mentioned, at least by his parents, except when there is an absolute necessity, and even in this case it must be whispered.[1029] This interdiction is frequently perpetual for the widow and certain relatives.[1030] Among certain peoples, this even extends beyond the family; all the individuals whose name is the same as that of the dead man must change theirs temporarily.[1031] But there is more than this: the relatives and intimate friends sometimes abstain from certain words in the usual language, undoubtedly because they were employed by the dead man; these gaps are filled in by means of periphrases or words taken from some foreign dialects.[1032] In addition to their public and everyday names all men have another which is kept a secret: the women and children do not know it; it is never used in the ordinary life. This is because it has a religious character.[1033] There are even ceremonies during which it is necessary to speak a special language which must not be used for profane purposes. It is the beginning of a sacred language.[1034]
