Burkina Faso and Michel Kafando was reinstated as Acting President. In the general election held on 29 November 2015, Roch Marc Christian Kaboré won in the first round with 53.5% of the vote and was sworn in as President on 29 December 2015. Formerly called the Republic of Upper Volta, the country was renamed "Burkina Faso" on 4 August 1984 by then-President Thomas Sankara. The words "Burkina" and "Faso" both stem from different languages spoken in the country: "Burkina" comes from Mossi and means "upright" showing how the people are proud of their integrity, while "Faso" comes from the Dyula language and
Kwa languages to the various Lagoon languages of southern Ivory Coast and to what are now called the Volta–Niger languages of southern Nigeria. Greenberg (1963) added the Kru languages of Liberia, the Ghana–Togo Mountain languages which Westermann and Bryan had specifically excluded, and Ijaw of the Niger delta; West Kwa included the languages from Liberia to Dahomey (Republic of Benin), and East Kwa the languages of Nigeria. Bennett & Sterk (1977) proposed that the Yoruboid and Igboid languages belonged in Benue–Congo rather than in Kwa. Stewart (1989) removed Kru, Ijaw, and Volta–Niger (East Kwa), but kept the Ghana–Togo Mountain and Lagoon languages,
