Formal:
* Níbo ni ile oogun tó súnmọ̀ mi wà? (Nibo ni ile oogun to sunmo mi wa?) - This is the most literal and formal way to ask.
* Níbo ni ile oogun tó sunmọ̀ mi jù lọ wà? (Nibo ni ile oogun to sunmo mi ju lo wa?) - This is also formal and emphasizes "closest."
Informal:
* Níbo ni ile oogun tó sunmọ̀ wà? (Nibo ni ile oogun to sunmo wa?) - This is less formal and assumes the listener understands you are asking about the closest pharmacy.
* Níbo ni àgọ́ tó súnmọ̀ mi wà? (Nibo ni ago to sunmo mi wa?) - This is more casual and uses a different word for "pharmacy" (ago).
Remember:
* "Níbo" means "where"
* "Ile oogun" means "pharmacy"
* "Tó sunmọ̀" means "closest"
* "Jù lọ" means "the most"
The choice of phrase depends on your relationship with the person you are talking to and the context of the conversation.
