Traditional grammar and current theoretical approaches towards modelling grammatical knowledge ignore language in interaction: that is, words such as huh, eh, yup or yessssss. This groundbreaking book addresses this gap by providing the first in-depth overview of approaches towards interactional language across different frameworks and linguistic sub-disciplines. Based on the insights that emerge, a formal framework is developed to discover and compare language in interaction across different languages: the interactional spine hypothesis. Two case-studies are presented: confirmationals (such as eh and huh) and response markers (such as yes and no), both of which show evidence for systematic grammatical knowledge. Assuming that language in interaction is regulated by grammatical knowledge sheds new light on old questions concerning the relation between language and thought and the relation between language and communication. It is essential reading for anyone interested in the relation between language, cognition and social interaction.

Using data from a variety of languages such as Blackfoot, Halkomelem, and Upper Austrian German, this book explores a range of grammatical categories and constructions, including tense, aspect, subjunctive, case and demonstratives. It presents a new theory of grammatical categories - the Universal Spine Hypothesis - and reinforces generative notions of Universal Grammar while accommodating insights from linguistic typology. In essence, this new theory shows that language-specific categories are built from a small set of universal categories and language-specific units of language. Throughout the book the Universal Spine Hypothesis is compared to two alternative theories - the Universal Base Hypothesis and the No Base Hypothesis. This valuable addition to the field will be welcomed by graduate students and researchers in linguistics.
