A study points out an idea, that a prerequisite of synonymy is a synonymous line as a place where an expression is in diverse semantic and stylistic relations with other members of the line. This is the way the author reasons for syntactic synonymy. On the basis of stylistic and pragmatic aspects he observes system and functional potential of syntactic variants of the synonymous line considering their semantic modifications but especially their stylistic nuances and functional potential. An analysis has shown that in spite of a limited number of the syntactic constructions, which result in a limited number of synonymous lines, syntactic synonymy - in addition to lexical synonymy - provides the biggest selection potential. This is another proof of an idea considering syntax as one of the most important style indicators.
