This book provides a collection of articles on subordination in English framed from both a synchronic and a diachronic perspective. It covers ample areas of the history of the major subordinated structures of English and their recent development in various native and non-native varieties. Most contributions are based on large electronic databases and corpora of written and spoken texts. The book focuses on the continuum that links subordinated and coordinated structures in a fluid way, shows their permanent state of flux, and sheds light on the whole system's dynamic essence by discussing a large number of explanatory principles at work in shaping it. Many of these are well-known from the grammaticalization and the Construction Grammar theories, such as the concepts of attractor, multi-sourcing, inheritance, categorial incursion, metaphorization or exaptation. This volume represents the latest trends in the field by some of its most prestigious specialists.
