Formal:
* Orúkọ rẹ̀ níbo ni? (o-ru-ko re ni-bo ni?)
Informal:
* Kí ló ń jẹ́? (ki lo n je?)
Here's a breakdown of the differences:
* Orúkọ rẹ̀ níbo ni? is a more polite and formal way to ask someone's name, similar to "What is your name?" in English. It literally translates to "Where is your name located?"
* Kí ló ń jẹ́? is a more casual and informal way to ask someone's name. It translates roughly to "What are you called?" or "What is your name?". This is a more common way to ask for someone's name among friends or family.
Important Note: In Yoruba, you can use either the formal or informal forms of "What is your name?" depending on the situation and your relationship with the person you are asking.
