By the way, I'd like to know if "lumi kuke" is a loan word. Because "lumi" sounds like "room" to me, and "kuke" sounds like "cook", and a room where you cook is a kitchen, so if that's a coincidence, it is very convenient! :)
Haha not a coincidence! Both words are loan words translated phonetically from English when the white man first came to Hawaiʻi.
They both mean in/on/at, although "i" is more of a directional location marker, which is how it is used describing actions being done towards something, or someone going somewhere. "Ma" is more generally used when stating the static location of something, like in this sentence.
Also translated as: 'Is he in the Kitchen?"
Is the intonation on 'ma ka lumi kuke' to make it a question?
