Yoruboid is a group of languages composed of Igala, a language spoken in central Nigeria, and the Edekiri group, the members of which are spoken in a band across Togo, Benin and southwestern Nigeria. The name Yoruboid derives from its most widely spoken member, Yoruba, which has more than 20 million speakers. Another well-known Yoruboid language is Itsekiri (Nigeria, 600,00-800,000 speakers). The Yoruboid group is a branch of Defoid, which itself is a branch of the Benue-Congo subfamily of the Niger-Congo language family.
