1. (verb) to trace a single line of descent from an ancestor without showing marriages.
Me tīmata noa i a Porourangi, ina hoki ōna kupu o mua, ko Hikurangi te maunga, ko Waiapu te wai, ko Ngāti Porou te iwi. He uri nō Porourangi. Me tararere noa kia mama ai (JPS 1950:286). / Let me begin with Porourangi because this is a well-known saying: Hikurangi is the mountain, Waiapu the river, Ngāti Porou the tribe. He is a descendant of Porourangi. Let me just trace the genealogy in a single line so that it is simplified.
