Proclitic-enclitic sequences in early Old Russian

This paper is addressed the issues in Slavic clitic syntax, with focus on clausal-initial proclitic-enclitic sequences in Old Russian. I argue that Early Old Russian in XI-XII centuries had a parameter setting licensing free clause-level accusative clitics including the reflexive marker ся and 1-3 p. clitic auxiliaries есмь, еси, есть, etc. after the clausal-initial conjunctions like и, a, нъ, да.
