The papers in this volume study linguistic structures in the context of their interactive functions and usages; they concentrate on grammatical constructions for the positioning of self and others. Using empirical analyses of positioning constructions, the authors show that forms and functions of grammatical structures in everyday interactions are closely interwoven with the conditions for the production and reception of spoken language. In order to take account of the tension between the stabilisation of grammatical constructions and the process of their actualisation in interactions, the authors combine methods from Interactional Linguistics with insights from usage-based positions of both Construction Grammar and Cognitive Grammar.
