Universal ways of presenting quantification-based polysituation are the number agreement/ disagreement, interval, frequency, verb quantification, etc. realized at the utterance level. This comparative analysis is aimed at revealing similarities and differences in the prototypical instances of expressing diachronic polysituation by the number disagreement in the French, English, Russian and Tatar languages. The prototyping analysis focuses on the most general patterns with no insight into special cases. Comparative analysis of the quantification relevance of various actants considers involvement of the actants in the expression of diachronic polysituation. This research project required consistent solution of three main objectives that outlined our work. First, exemplifying prototypical sentences with action verb predicates, we specified the role of actants with semantically different functions in communication of diachronic polysituation via the number disagreement. Second, we carried out an analysis to identify the role of quantification of object-type actants and the spatial localizer with the algorithm: 1) Object; 2) Instrument; 3) Action Localizer; 4) Situation Localizer; 5) Recipient. Finally, we singled out object-type actants, the quantification of which leads to the representation of diachrony.
