"Ó ra așo tuntun" jé apeere gbolohun ...?

Yoruba sentences are classified by the purpose they serve: a declarative sentence states a fact or gives information, an interrogative sentence asks a question, and an imperative sentence gives a command. "Ó ra aṣọ tuntun" (He bought new clothes) simply reports an event that took place, without asking anything or instructing anyone to act.

Because it states information rather than questioning or commanding, this sentence is a declarative sentence, called gbolohun àfihàn in Yoruba grammar, which is the correct classification.

It cannot be a question, since it contains no question word or rising interrogative structure, and it cannot be a command, since it describes a completed action rather than instructing someone to act. Checking whether a Yoruba sentence states, asks, or instructs is the quickest way to sort it into its correct grammatical type.
