There are three constructions in Guinean Maninka with basic meanings belonging to the future-prospective area: the First Future, the Second Future, and the Prospective.

Additionally, it establishes that the First Future and Prospective constructions are sensitive to the presence of an argument focus in the clause. Finally, it advances hypotheses on the etymology and the evolution paths of each construction and its marker: the Prospective construction may origin
