In ordinary conversation the general ongo, boy, and oka, lass, are used instead of the formal terms otsotyungo and otsolovo. In the case of a woman speaking of her brother’s child ongo and oka are invariably used instead of otsotyungo and otsolovo in order to avoid any suggestion of marital relations with her brother. The terms orapfu and eng are rarely used in address, or when a man or woman is speaking of his or her own wife or husband. Instead, okikhamo (m.) and okikhamm (f.), meaning “house-mate,” are substituted. Though they may be of a different phratry there are certain women whom a man may not marry. (1) His mother’s sister’s daughter, even if his mother’s sister has married into another clan, for he calls his mother’s sister oyoramo (“big mother”) or oyonunghowo (“little mother”); (2) his own sister’s daughter (orrhovo); (3) his father’s sister’s daughter (orrhovo); but he can marry his mother’s brother’s daughter (oyonunghowo). A man is rather expected to take his wife from his mother’s clan. There is no fine for not doing so, but his mother’s clan are likely to take offence. He is fined if, having taken one wife from his mother’s clan, he takes a new one from another clan. The fine amounts to about Rs. 5, and is called lolang ’ntyakma (the price of not taking from the mother’s clan). A man is not bound to marry his deceased brother’s wife, but he may do so if he wishes without paying any marriage price. He may also marry his father’s widow provided that she is not his own mother, but such marriages, though pretty common, are viewed with a certain amount of disfavour.
