Linguistics investigates the systems underlying language, speech, and language use. Linguists seek to develop an understanding of the rules and laws that govern the structure and use of particular languages and the manner in which these interact with internal systems and processes (interpretation, speech perception, and production) and with the outside world (acquisition, use, change and role in society). The articles in this volume present an addition to answering three important questions about knowledge in linguistics: What is knowledge in linguistics, how is it acquired, and how is it put to use? Apart from the data on the specific phenomena addressed in the articles, the book presents insight into the palette of present-day linguistics. In this way, it aims to break open the division of linguistics into subfields thereby making possible cross-fertilisation.
