Yan ọ̀rò tí ó wúlò gégẹ́ bí orúkọ:

This question tests the ability to identify which word in a set functions as a noun, "orúkọ" in Yoruba grammar, as opposed to a verb.

Three of the words describe actions: singing, going, and eating, and each behaves as a verb because it can only complete a sentence when paired with a subject performing the action, for example "o kọrin," "o lọ," or "o jẹ." The remaining word names a thing, a dwelling or house, and can stand as the subject or object of a sentence on its own, for example "ilé náà tóbi," the house is big. That grammatical behaviour, naming a person, place, or thing rather than an action, is what marks it as the noun in this group.

A quick test for separating nouns from verbs in Yoruba is to ask whether the word can be preceded by a determiner such as "náà" ("the") or a quantity word; only a noun accepts that construction naturally.

When asked to pick out a noun among Yoruba words, check first whether each word denotes an action or a thing, since that single distinction settles most of these questions quickly.
