This paper addresses the following topics within the framework of natural grammar: On the paradigmatic level of the analysis (The Part titled “Semantics of aspectual-temporal forms of Russian verb”), the temporal and aspectual meanings of each aspectual-temporal form contained in the system of Russian aspectual-temporal forms are determined. On the syntagmatic level of the analysis (The Part titled “Pragmatics of aspectual-temporal forms in Russian”), the use of aspectual-temporal forms in standard and non-standard contexts is investigated as exemplified by performative verbs in the perfective future.
