From noun to future tense

Abstract This article explores a typologically unusual but recurrent evolutionary path of innovated future formations neglected by typological research: the change of predicative deverbal nouns (understood here in the broad sense of any deverbal nominal expression/formation) – namely agent nouns and participles – denoting actions typical of referents to future verb-forms via hypoanalysis. Starting with an overview of typologically recurrent ways of creating new future formations, the article seeks to demonstrate that the l-future found in the three Nuristani languages Nuristani Kalasha, Ashkun and Katë developed from active participles designating actions typical of their referents. As a typological parallel of this development the Vedic Sanskrit tā́-future is established, and it is shown by the example of the English will + infinitive future and the futurate use of Russian perfective non-past verb-forms how the change of predicative deverbal nouns denoting actions typical of referents to future verb-forms is brought about by means of hypoanalysis.
