Similar terms are often used for other relationships. The Greek, “πάππος” signifies grandfather, and “μάμμα” grandmother. In the Kanúri language, “yaya” stands for elder brother;[458] and, in Lifuan, “mama” and “dhina” are terms for brother, whilst mother is “thine.”[459]
The origin of such terms is obvious. They are formed from the easiest sounds a child can produce. “‘Pa-pa,’ ‘ma-ma,‘ 'tata,’ and ‘apa,’ ‘ama,’ ‘ata,’” Professor Preyer says, “emerge originally spontaneously, the way of the breath being barred at the expiration, either by the lips (_p_, _m_), or by the tongue (_d_, _t_).”[460] Yet the different races vary considerably with regard to the ease with which they produce certain sounds. Thus the pronunciation of the labials is very difficult to many Indians,[461] on account of which their terms for father, mother, or other near kinsfolk, often differ much from the types given by Professor Buschmann.
It is evident that the terms borrowed from the children’s lips have no intrinsic meaning whatever. Hence, if a Bakaĭri child calls its father and father’s brother “tsogo,” its mother and mother’s sister “tsego”;[462] if a Macúsi names his paternal uncle “papa” as well as his father, and an Efatese names his father and all the tribe brothers of his father “ava” or “tama”;[463] if the Dacotahs apply the term “ahta” not only to the father, but also to the father’s brother, to the mother’s sister’s husband, to the father’s father’s brother’s son, &c., and the term “enah” not only to the mother, but also to the mother’s sister, to the mother’s mother’s sister’s daughter, &c.;[464] if, among the New Caledonians, an uncle, taking the place of a father, is called “baba” like the father himself, and an aunt is called “gnagna” like a mother;[465] if, as Archdeacon Hodgson of Zanzibar, writes to me, a native of Eastern Central Africa uses the words “baba” and “mama” not only for father and mother respectively, but also, very commonly, for “any near relationship or even external connection;” if, finally, the Semitic word for father, “ab” (“abu”), is not only used in a wide range of senses, but, to quote Professor Robertson Smith, “in all dialects is used in senses quite inconsistent with the idea that procreator is the radical meaning of the word,”[466]—we certainly must not, from these designations, infer anything as to early marriage customs.
