brother of a girl

He kaha tōku tungāne.
My brother is strong.
- this is an example of a classifying sentence

Note that this is a term that a female speaker would use to refer to her brother.  To refer to his brother (or male cousins), a male speaker would use the terms tuakana (elder sibling) or teina (younger sibling).  These two terms may also be used by female speakers to refer to their sisters and female cousins.

Alternatively, speakers of either sex might use the terms mātāmua (eldest) or pōtiki (youngest).  

A male speaker may use tungāne to refer to the brother of a woman, for example,

Ko te tungāne o Ngaire ia.
He is Ngaire’s brother.
