The contributions in this volume provide a kaleidoscope of state-of-the-art research in corpus linguistics on lexis and lexicogrammar. Central issues are the presentation of major corpus resources (both corpora and software tools), the findings (especially about frequency) which are simply not accessible without such resources, their theoretical implications relating to both lexical units and word meanings, and the practical – especially pedagogical – applications of corpus findings. This is complemented by a lexicographer’s view on the data structures implicit in the Oxford English Dictionary (OED). The volume, which has sprung from the 36th ICAME conference, held in at Trier University in May 2015, will be of relevance for theoretical and applied linguists interested in corpora, word usage, and the mental lexicon.
