Eré onígbàgbọ́ ni ...?

The word onígbàgbọ́ means a believer, someone who practises a religious faith. When it qualifies eré (a play or dramatic performance), it marks out a play whose content and structure are built around worship rather than around a secular theme.

A play of this kind is organised the way a service of worship is organised, carrying prayer, scripture, preaching, and religious song within its scenes. That is why the performance described this way is one that has a programme of worship running through it, and not a play about national education, a musical news report, or a general story about the origin of the world, since none of those are defined by a religious structure.

When a Yoruba vocabulary question qualifies eré with the name of a group of people, look for the option that names the activity that defines that group. For believers, that activity is worship.
