In recent years, issues of verbal valency, valency alternations and verb classes have seen a new upsurge of interest from a variety of perspectives. This book comprises articles investigating valency phenomena on a contrastive basis within Romance, Germanic and Slavic, and also in Basque and in the West-African language Ga, as well as classical Greek and Sanskrit. Phenomena include transitive and ditransitive constructions and alternations, involving reflexives, cognate objects, ’null’ objects, case (in its syntagmatic and paradigmatic aspects), and infinitives, mostly in a synchronic perspective. Aiming at a closer understanding of the range of regularities falling within the concept of valency frames, the book offers a representative array of current assumptions, hypotheses, methodologies and new findings within the overall field. The volume will provide a valuable resource for researchers and students both in general linguistics and in the relevant language particular disciplines.
