Specialist languages, such as the languages of law, business, aviation, football, and politics, can be perceived as highly conventionalized, semi-natural and not fully autonomous communication codes limited to specific, and predominantly formal, situations. A large number of them can be best characterized by subject matter and semantic content, but the most important distinctive element in their make-up is the frame of context in which they are embedded. This volume discusses various ways of approaching the problems associated with the very broad phenomenon of specialist languages by means of the analytical mechanisms and theoretical conceptions developed within the framework of Cognitive Linguistics. The volume includes research carried out by world-renowned experts in the field.
