In contrast to Cree, Tsu'u Tina have relatively fewer words for kin relationships. Marriage with first cousins is not allowed, since first cousins are known as brothers and sisters, while aunts and uncles on both sides, with the exception of mother's sister (who was simply mother) are regarded as older brothers and sisters. Likewise nieces and nephews are regarded as younger brothers and sisters, while smaller related children are sons and daughters. There are unique terms for older and younger brothers and sisters.
