On an understudied verbal form of future with prospective semantics in Tuvan.

The article proposes an analysis of a verbal form in the Tuvan language used to express future, prospective semantics and some modal meanings, which has never been described in Tuvan grammars. The form derives from the future participle -r and possessive affixes used in this case as personal markers. The additional (and optional as well) component is the particle ol, which can be omitted with no effect on the interpretation of the construction. This verbal form has developed as a result of grammaticalization of a polypredicative construction.
