The article analyzes new phenomena of the use of three main types of verb formations, namely inflected or morphological verbs, infinitives, and predicative forms in -nо, -tо, found linguistic and non-linguistic factors of grammatical dynamics, evaluates the changes that have occurred in the background of prescriptive grammatical norms. It has ascertained a return to the active normative use of the first person plural form of the imperative in -mо, -іmо with the meaning of encouragement to joint action, which is especially noticeable in the exhortation-motivational discourses of the mass communication media, and the forms of the motivational mood as explicators of a non-categorical urge to perform a certain action. The widespread use of auxiliary verbs мати with the modal meaning of obligation and хотіти with the meaning of intention to do something in the structure of verbal compound predicates was evaluated from the normative perspective. The tendency towards more active use was noted infinitives in creating the synthetic (simple) form of the future tense and the subsequent competition of the infinitive and the corresponding noun in the object position. The paper substantiates the wide use of infinitives in the role of the simple infinitive main member with a particle by (b) to express the desired action or desired state for the speakers and as a function of the lexical-semantic component combined with the modal words треба, потрібно, варто, можна in the structure of the compound main member of infinitive monosyllabic sentences. The research has defined new parameters and unresolved issues of reactualization of predicative forms in -nо, -tо in scientific texts, the official business sphere, and mass media.
