"Kimo is a lively brother of a sister."
Translation:He kaikunāne ʻeleu ʻo Kimo.
...(kaikunāne) means brother, and (kaikuahine) means sister. However, ... these terms apply specifically to the brother of a girl, or the sister of a boy.
This means that if you are a boy and want to refer to your brother , you need to identify whether he is your older brother (kaikuaʻana) or younger brother (kaikaina). ...the same terms are used to identify the older and younger sister of a girl.
