Hawaiian Word of the Day: June 12th By Leilani Poli`ahu • Jun 12, 2019 ShareTweetEmail Listen Listening... / 0:31 Papaheʻenalu. Well Papa can mean a "board or almost any kind of flat surface." Adding heʻenalu to it makes it a surfboard. Heʻe means "to slide or surf," and nalu means "wave." Put it all together and you get a surfboard.
