This article studies syntactic, semantic and discursive properties of non-subordinate (main) clauses conveying possession in Oghuz and Kipchak Turkic languages. In Turkic, the concept of possession is typically encoded by clauses based on existential predicates. The language-specific and crosslinguistic properties of two predicate types, {bar} and {bol}, will be contrastively surveyed. As for the marking of possessor in clauses containing {bar}, three patterns will be described, one of which is a contact-induced structure restricted to Turkic varieties in Iran. As a multifunctional verb, {bol} can convey, among other things, dynamic or static possession. The results indicate that the clauses based on the static possession marker {bol} are more operative in Kipchak languages and in Turkmen (East Oghuz), than in West Oghuz languages. It will further be shown that the structures based on {bar} or the static marker {bol} typically exhibit discourse-related distribution in the respective languages.
