Variability, variance is observed at all levels of the language as a universal feature of language means. One of the key features for the contemporary linguistic research is to focus a spotlight on the issues concerning the general typology of variability of language means and functional specifications of various variants in the text. In contrast to other levels of language, the problem of variability in syntax has not been extensively studied. The complexity of the investigation of variability in syntax is conditioned by the dual nature of syntactic units, and their structure and content layout.
