ABSTRACT
In this chapter we share some of what we find valuable about the study of grammar as sets of practices adapted to social interaction. Clearly, we are not able to cover all the fascinating and fruitful research that has appeared in this area in recent years, but we hope, through several examples from our own work and through references to other research, to spark further interest in the reader. To begin with, let us consider how we conceive of grammar and then how that relates to the centrality of social interaction as a major habitat to which grammar is adapted.
