This volume grew out of the 34th International LAUD Symposium, which was held in March 2010 at the University of Koblenz-Landau in Landau, Germany. The symposium was dedicated to the ongoing convergence between the disciplines of Cognitive Linguistics and Sociolinguistics, bringing together concepts and methods from both fields. The 15 studies contained in this volume explore the relations between linguistic (structural), socio-cultural and cognitive aspects involved in language variation. Methodologically, the contributions range from individual case studies to larger-scale corpus analyses and combine both qualitative and quantitative findings.
