Formal/Neutral:
* Kí ni ó ṣẹ̀ sí? (Ki ni o se si?) - This is the most direct translation and is generally suitable for most situations.
Informal/More Casual:
* Kí ló ṣẹ̀ sí? (Ki lo se si?) - This is a shortened version of the formal phrase and is more casual.
* Kí ló ṣẹ́ lára...? (Ki lo se lara...?) - This specifically asks what is wrong with someone's health or well-being.
Expressing Concern:
* Kí ló ń ṣẹ̀ sí...? (Ki lo n se si...?) - This adds a sense of ongoing trouble or worry.
* Kí ló ń ṣẹ́ lára...? (Ki lo n se lara...?) - Similar to the above, but specifically asks what is wrong with someone's health in an ongoing sense.
Other Variations:
* Kí ló ṣẹ̀...? (Ki lo se...?) - This is a more general question asking what's wrong, without specifying.
* Kí ló ṣẹ̀ sí...? (Ki lo se si...?) - This can be used in more accusatory situations, implying that there is something wrong with the person or situation.
Remember to:
* Use the appropriate tone and context when saying these phrases.
* Add the relevant noun/pronoun after the phrase, for example: "Kí ló ṣẹ̀ sí óun?" (What's wrong with him?)
* Consider using the plural form if asking about multiple things, for example: "Kí ló ṣẹ̀ sí wọn?" (What's wrong with them?)
These are just a few examples, and the best way to understand the nuances is to hear and use the language in context.
