Here are some ways to use it in a sentence:
* Ke aʻo nei au i ka ʻōlelo Hawaiʻi. (I am teaching the Hawaiian language.)
* He kumu aʻo ʻo ia. (He/She is a teacher.)
* He ʻano aʻo hou kēia. (This is a new teaching method.)
You can also use the phrase "ke aʻo ʻana" which means "the act of teaching". For example:
* Ke ʻike nei au i ka pono o ke aʻo ʻana. (I see the value of teaching.)
It's important to note that the pronunciation of Hawaiian words can be tricky. You'll want to practice saying "aʻo" with the correct pronunciation, which is similar to the sound of "ah-oh".
