CRITERIA FOR DISTINGUISHING OF INFINITIVES AND MODAL WORDS
The paper proposes a set of criteria to distinguish between functional and functional-semantic homonyms, formed as a result modulation of infinitive forms of the verb in the Russian language. As the main criterion is recognized grammatical semantics of verbs (in the form of infinitives) and modal words. It is the presence of the verbal action values have infinitives predetermines the realization of grammatical categories of the type and pledge actional level and others. At the same time, the appearance of infinitives in the introductory use of subjective-modal semantics may lead to desemantisation and opportunities ellipsis in speech without losing the common sense proposition, as well as to eliminate (neutralize) the most important properties of the verb, namely, the values of the action and their means of expression – the category and type of collateral. The starting premise is recognized speed nature of the process modalation infinitives, and nuclear generating peripheral modalates, and hybrid structures, which occupy an intermediate position between the verbs and input modal words. Particular attention is drawn to the syncretic word-form, operating in syncretic contexts of modalation, predicativation and conjunctionalisation and in the zone of interaction of classes of words and semantic-syntactic between-classes-of-wordal discharges – verbs, modal words, predicatives and unions.
