In the past decade, Cognitive Linguistics has developed into one of the most dynamic and attractive frameworks within theoretical and descriptive linguistics. With about fifty chapters written by experts in the field, the Oxford Handbook of Cognitive Linguistics intends to provide a comprehensive overview of the entire domain of Cognitive Linguistics, from basic concepts to practical applications. We thank the publisher, Oxford University Press, and its responsible editor, Peter Ohlin, for the initiative they took to commission this reference work and for the subsequent freedom they gave us in shaping it. .
