Substantial and Qualificative Indefinite Additive Syntaxema Options

Syntactic units in indefinite pronouns were analyzed separately by syntax. Their categorical differential syntactic-semantic features were revealed, and on the basis of the features, depending on the position of indefinite pronouns in a sentence, substantial and qualificative indefinite additive syntactic variants were distinguished from noncategorical featutes. Various transformation methods have been used to define additive syntax variants. Addition and subtraction methods were used.
