"Let's cook the taro."
Translation:E hoʻomoʻa kākou i ke kalo.
My dictionary refers to moʻa, which means cooked or burned, as by the sun. Moʻa acts as the stem, and hoʻo- is a common prefix before (stem) words beginning with i, u, and all consonants except the ʻokina. It suggests causation. Kuke also means cook or to cook as one of its meanings. It sounds so much like "cook" that I suspect it is a word borrowed from English, but thatʻs just a guess.
