Biifinitive sentences together with the binomial sentences group also form a group of binary sentences. The author believes that the predication of biifinitive sentences can be defined as a composite infinitive predicate. Biinfinitive sentences are organized by the method of analytics. The relevance of the designated theme is due to its relevance to a number of “controversial” issues of modern Russian syntax: the problem of subject, compound predicate, predicativity and potential polypredicativity the distinction between single and double sentences, punctuation design infinitive-suitable proposals, etc.
