Long regarded as a peripheral issue, phraseology is now taking centre stage in a wide range of fields. This recent explosion of interest undoubtedly has a great deal to do with the development of corpus linguistics research, which has both demonstrated the key role of phraseological expressions in language and provided researchers with automated methods of extraction and analysis. The aim of this volume is to take stock of current research in phraseology from a variety of perspectives: theoretical, descriptive, contrastive, cultural, lexicographic and computational. It contains overview chapters by leading experts in the field and a series of case studies focusing on a wide range of multiword units: collocations, similes, idioms, routine formulae and recurrent phrases. The volume is an invitation for experienced phraseologists to look at the field with different eyes and a useful introduction for the many researchers who are intrigued by phraseology but need help in finding their way in this rich but complex domain.
