The question asks for the English equivalent of the Igbo term akuko ifo.
Akuko means "story" or "narrative," and ifo refers to something imaginary, fictional, or from oral tradition. Together, akuko ifo specifically denotes traditional stories passed down orally within a community - stories that carry moral lessons and feature characters such as talking animals, spirits, and humans in fictional scenarios. The precise English term for this genre is Folktale.
While the other English options are related to narrative, they are not precise equivalents:
Tale is a general word for any story and is too broad
Myth refers specifically to stories about gods, creation, and the origin of the world (akuko okike in Igbo) - a different category
Story is the most generic term and could refer to any narrative, fictional or factual
Folktale is the standard English translation of akuko ifo in Igbo literary studies.
