Why “tuakana” is a great word
TUAKANA — [Noun] In Māori kinship, the elder sibling of the same sex, or a same-sex cousin from a more senior branch of the family, who holds a position of inherent guidance and authority. Borrowed from Māori tuakana, a term common across Polynesian languages (e.g., Cook Islands Māori tuākana, Hawaiian kaikuaʻana) for an elder same-sex sibling. Unlike *teina* (which denotes the reciprocal junior role) or *mentor* (a chosen advisor lacking inherent kinship obligation), tuakana is a title conferred by birth and lineage, carrying the weight of duty and precedent. It is the steady hand guiding the younger’s first paddle-stroke in the waka, the quiet voice correcting a sister’s weaving pattern before the error is set, the shoulder that bears the expectation of an entire lineage—a bond that is less a choice than a law written in blood and belonging.
