"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. (Page 179, Hawaiian Language Fundamentals ʻŌLELO ʻŌIWI, Hōkūlani Cleeland)
kaikunāne = brother of a sister
Before I noticed the part about Kealoha and Komo (good clue!) I was wondering what the difference between kunāne and kaikunāne was, because they were both "brother or male cousin of a female"... Now I see they are variations: kunāne — Pukui-Elbert, Haw to Eng, n. Brother or male cousin of a female, usually used only as term of address or as an affectionate variation of kaikunāne. (PPN tu(o)ngaʻane).
