This book examines how knowledge is created in key areas of day-to-day practice with the aid of linguistic means. Using examples from medicine, law, teaching/learning interactions and mass media, the book investigates what is displayed interactively as knowledge and/or what is considered to be knowledge. The book is divided into four sections which discuss the following key questions: how is knowledge embedded in the respective situation, how is knowledge brought forth interactively, how do institutions present knowledge effectively and how is knowledge disseminated in the (mass) media?
