How do you say hi and bye in African?

It's not accurate to say "hi" and "bye" in "African" because Africa is a vast continent with hundreds of languages and dialects.

To say hello and goodbye in a specific African language, you need to specify the language. For example:

* Swahili:

* Hello: Jambo (formal), Habari (informal)

* Goodbye: Kwaheri (formal), Kwenda salama (informal)

* Yoruba (Nigeria):

* Hello: E kaabo (formal), Mo ki o (informal)

* Goodbye: E ku ire o (formal), O daabo (informal)

* Zulu (South Africa):

* Hello: Sawubona (formal), Sanibona (informal)

* Goodbye: Sala kahle (formal), Hamba kahle (informal)

It's important to note that these are just a few examples. To be respectful, it's best to learn the appropriate greetings and farewells in the specific language of the person you are speaking to.
