How do you say Have a nice day in Yoruba language?

There are a couple of ways to say "Have a nice day" in Yoruba, depending on the context and level of formality:

Formal:

* "Kí o ní ọjọ́ tí ó dára" (Kee oh nee ojo tee oh dah-rah) - This is a very formal and polite way to say it.

Informal:

* "Ojú àbọ̀ rẹ̀ dára" (Oh-joo ah-boh reh dah-rah) - This translates literally to "May your day be good," and is more casual.

* "Máa ní ọjọ́ tí ó dára" (Mah nee ojo tee oh dah-rah) - This is a more direct way to say "Have a nice day" and is appropriate for friends and family.

You can also add a personal touch by saying something like:

* "Mo gbàdúrà pé kí o ní ọjọ́ tí ó dára" (Moh gbah-doo-rah pee kee oh nee ojo tee oh dah-rah) - This means "I pray that you have a nice day."

The best choice will depend on who you are talking to and the context of the conversation.
