The name
Yoruboid derived from its most widely spoken member,
Yoruba, which has around 55 million primary and secondary speakers. Another well-known Yoruboid language is
Itsekiri (about 1,000,000 speakers). The Yoruboid group is a branch of
Defoid, which also includes the
Akoko and
Ayere-Ahan languages. The term
Defoid itself is a derivative combination using the elements
ede (meaning 'language' in most lects within the grouping), "
Ifẹ", a city of profound cultural significance to speakers of the diverse lects, and
-oid, a suffix meaning 'to be like' or 'in the same manner as'. The
Defoid group itself is a branch of the
Benue–Congo subfamily of the wider
Niger–Congo family of languages. All Yoruboid languages are tonal, with most of them having three level tones. Grammatically, they are isolating with a subject–verb–object basic word order and share significant degrees of both structural and lexical similarities. ==Languages==
