"Kààbọ̀ọ̀" (pronounced kah-boh)
You can also say:
"È kààbọ̀" (pronounced eh kah-boh) which is a more formal way of saying good morning.
It's important to note that in Yoruba, greetings are usually followed by a question about the person's well-being. You can say something like:
* "Bawo ni?" (pronounced bah-woh ni?) - "How are you?"
Or, if you want to be more formal:
* "Bawo ni o?" (pronounced bah-woh ni oh?) - "How are you?"
