A central debate about the description of auxiliary selection concerns the regularity of auxiliary selection from a typological perspective. Thus, studies of auxiliary selection have both stressed the fact that certain recurrent parameters are highly relevant to the description of auxiliary selection, whereas other studies demonstrate significant differences in auxiliary selection systems.
By integrating the synchronic and diachronic levels of linguistic description, the papers in the present volume work towards a framework that explains these contradictory findings. They discuss the role of semantic and syntactic constraints in gradient auxiliary selection, address the question of paradigmaticity of the

alternation, and shed light on the mechanisms of the gradual historical change from

The volume thus puts forth a row of innovative theoretical and empirical findings from a wide range of typologically diverse European languages that substantially broaden our knowledge about the mechanisms of auxiliary selection systems.
