Formerly 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" 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 Dioula language (as written in N'Ko:  ''faso'') and means "fatherland" (literally, "father's house"). The "-bè" suffix added onto "Burkina" to form the demonym "Burkinabè" comes from the Fula language and means "women or men". The CIA summarizes the etymology as "land of the honest (incorruptible) men".
