How do you say What is this in Yoruba language?

There are a few ways to say "What is this?" in Yoruba, depending on the context and level of formality:

Formal:

* Kí ni èyí? (kee nee ee-yee?) This is the most common and formal way to ask.

Informal:

* Èyí kọ́? (ee-yee ko?) This is a more informal and casual way to ask.

* Kí ni èyí gan-an? (kee nee ee-yee gan-an?) This is a slightly more emphatic way to ask, similar to "What exactly is this?"

Note:

* Kí (kee) means "what"

* ni (nee) means "is"

* èyí (ee-yee) means "this"

The intonation and stress on the words can also influence the meaning and tone of the question.
