For getting someone's attention:
* "E komo mai" (eh koh-moh my) - This literally means "come in" and is used to politely get someone's attention.
For apologizing for bumping into someone:
* "E kala mai" (eh ka-la my) - This means "please forgive me" and is a more formal way of apologizing.
* "E kala" (eh ka-la) - A shorter and more informal version of "E kala mai".
For interrupting someone:
* "E ho'omaika'i" (eh ho-o-my-ka-ee) - This means "excuse me" in the sense of asking to interrupt someone.
* "E ho'omaika'i, ke noi aku nei au" (eh ho-o-my-ka-ee, keh noy-ee a-koo nay-ee ow) - This is a more polite way to interrupt, meaning "Excuse me, I would like to ask..."
It's important to note that context and tone matter a lot in Hawaiian. You can often convey "excuse me" by simply using a friendly tone of voice and a respectful gesture.
