The '''Kwa languages''' are spoken in the south-eastern part of [[Côte d'Ivoire]], in [[Ghana]], [[Togo]] and [[Benin]], and the south-Western corner of [[Nigeria]]. The term was introduced [] by [[Krause]] and used by [[Diedrich Hermann Westermann|Westermann]] (1952) and [[Joseph Greenberg|Greenberg]] (1963). It is derived form the word for 'people' in many of these languages, which contains the root ''kwa''. The Kwa group of languages is a branch of [[Volta-Congo]] and ultimately [[Niger-Congo]].
Bennett & Sterk (1977) argued that Kwa in its original form was not a genetic unit, and proposed a reclassification in which the [[Defoid languages|Yoruboid]] and [[Igboid languages|Igboid]] languages are members of the [[Benue-Congo languages|Benue-Congo subfamily]]. The remaining languages are sometimes labeled ''New Kwa'' in order to avoid confusion with the old, larger Kwa family.
The Kwa languages are divided into two groups: [[Nyo languages|Nyo]] and [[Left bank languages|Left bank]]. The Nyo group comprises about 50 languages mainly spoken in [[Ghana]] and southern Côte d'Ivoire; it includes the [[Akan languages]], [[Ga language|Ga]]-[[Dangme language|Dangme]], [[Anyi languages|Anyi]], [[Baule language|Baule]], and the numerous [[Potou-Tano languages|Potou-Tano]] languages (including the [[Guang languages]] and [[Logba language|Logba]])
The remaining Kwa languages are called ''Left bank'' because they are spoken on the Eastern side of the [[Volta River]] in Ghana, Togo, Benin and southwestern Nigeria. Of this group of about 25 languages, the [[Gbe languages|Gbe cluster]] is the largest with some five million speakers; other languages include Avatime, Nyangbo-Tafi and Animere.
