"He is in the kitchen."
Translation:Aia ʻo ia i ka lumi kuke.
Try not to feel the need to put an English meaning to every word in Hawaiian. You can think of it that way with the dictionary meaning. However, aia really does not have a meaning in English. It is just commonly used to start sentences about the location of nouns. There are other ways to say there, such as laila or ʻō, that are closer to the way we say there in English..
