This book sheds new light on the nature of gerunds in English, utilizing data from very large electronic corpora in order to compare pairs of patterns viewed as constructions. It serves as a contribution to the study of complementation, an under-researched area of investigation which bridges observations at the intersection of lexico-grammar, syntax and semantics. As a result, the reader develops their understanding of the meaning and use of each pattern within the system of English predicate complementation as it has evolved in recent times. This book will be of interest to students and scholars of English linguistics, especially English grammar.
