Rethinking the Role of Invited Inferencing in Change from the Perspective of Interactional Texts

The hypothesis that “invited inferences” are factors in change and challenges to it are reviewed. In light of recent work on historical construction grammar and interactional discourse analysis, I suggest that at least three types of inferences play a role in interactional contexts: local inferences associated with specific expressions; discourse structuring inferences pertaining to factors like coherence, backgrounding and foregrounding; and turn-taking inferences associated with turn relevant positions. A case study tests this suggestion: the development of discourse structuring uses of a family of Look expressions. Turn-taking has been regarded as a trigger in related changes. However, in this case not turn-taking, but rather a profile shift associated with non-use of complementizers is hypothesized to be a crucial enabling factor
