Transient subordinate clauses in Balkan Turkic in its shift to Standard Average European subordination. Dialectal and historical evidence

Abstract The Turkic varieties of the Balkans use two main diametrically opposed subordination strategies: (i) the Turkic model, where typical subordinate clauses are prepositive, nonfinite, contain clause-final subordinators, etc. and (ii) the Indo-European model, where typical subordinate clauses are postpositive, finite, contain clause-initial subordinators, etc. The paper observes that Balkan Turkic additionally uses several kinds of subordinate clause that allow for problematic mixtures of these two models (‘X-clauses’). Spread over a spectrum between the Turkic and Indo-European extremes, X-clauses can, for instance, be prepositive but contain clause-initial subordinators. The paper, then, hypothesizes that X-clauses emerge due to uncertainties in the structural parameters of the Balkan Turkic subordination system. Such uncertainties are typical of complex systems undergoing change and arise in the present case due to the shift in Balkan Turkic away from Turkic towards Indo-European subordination.
