Kwa languages

[1] Stewart[2] distinguished the following major branches, which historical-comparative analysis supports as valid groups: The Lagoon languages of southern Ivory Coast are not particularly close to any of these, nor to each other, so they are left ungrouped: An Esuma language, extinct ca.

Since Stewart, Ega has been tentatively removed, the Gbe languages reassigned to Volta–Niger, and Apro added.

Ethnologue divides the Kwa languages into two broad geographical groupings: Nyo and Left bank, but this is not a genealogical classification.

The Nyo group collapses Stewart's Potou–Tano and Ga–Dangme branches and also includes the ungrouped languages of southern Ivory Coast, while the Ka/Na-Togo and Gbe languages are called Left bank because they are spoken to the east of the Volta River.

Bennett & Sterk (1977) proposed that the Yoruboid and Igboid languages belonged in Benue–Congo rather than in Kwa.
