Distinguished scholars examine the phenomena of passives and causatives in languages from around the world.

This volume surveys a variety of verb valency change phenomena among diverse languages and from diverse theoretical viewpoints. It offers typological studies comparing languages in topics like applicative polysemy, complex predicate formation and locative alternation, but also works describing the different valency-changing operations in specific languages including West Circassian, Huasteca Nahuatl, Tlachichilco Tepehua and Seri, and works dealing with specific valency change constructions, such as tla- constructions in Nahuatl, resultatives in Yaqui, antipassives in Mocoví, and labile verbs in Arabic. This book aims to put this variety of backdrops in perspective and to clarify the notion and mechanisms of verb valency change. Both scholars and expert readers will get in these works a better understanding of the different verb valency changing operations and of the typological aspects involved in this phenomenon, together with a better grasp of how argument realization and verb morphology are connected in some languages.

Valency patterns and valency orientation have been frequent topics of research under different perspectives, often poorly connected. Diachronic studies on these topics is even less systematic than synchronic ones. The papers in this book bring together two strands of research on valency, i.e. the description of valency patterns as worked out in the Leipzig Valency Classes Project (ValPaL), and the assessment of a language's basic valency and its possible orientation. Notably, the ValPaL does not provide diachronic information concerning the valency patterns investigated: one of the aims of the book is to supplement the available data with data from historical stages of languages, in order to make it profitably exploitable for diachronic research. In addition, new research on the diachrony of basic valency and valency alternations can deepen our understanding of mechanisms of language change and of the propensity of languages or language families to exploit different constructional patterns related to transitivity.

The three concepts of case, valency and transitivity belong to the most discussed topics of modern linguistics. On the one hand, they are crucially connected with morphological aspects of the clause, including case marking, person agreement and voice. On the other hand, they are related to several semantic issues such as the meaning of case, semantico-syntactic verbal classes, and the semantic correlates of transitivity. The volume unifies papers written within different theoretical frameworks and representing variegated approaches (Optimality Theory, Government and Binding, various versions of the Functional approach, Cross-linguistic and Typological analyses), containing both numerous new findings in individual languages and valuable observations and generalizations related to case, valency and transitivity.

Valency and Molecular Structure, Fourth Edition provides a comprehensive historical background and experimental foundations of theories and methods relating to valency and molecular structures. In this edition, the chapter on Bohr theory has been removed while some sections, such as structures of crystalline solids, have been expanded. Details of structures have also been revised and extended using the best available values for bond lengths and bond angles. Recent developments are mostly noted in the chapter on complex compounds, while a new chapter has been added to serve as an introduction to the spectroscopy of complex compounds. Other topics include the experimental foundation of the quantum theory; molecular-orbital method; ionic, hydrogen, and metallic bonds; structures of some simple inorganic compounds; and electronic spectra of transition-metal complexes. This publication is a useful reference for undergraduate students majoring in chemistry and other affiliated science subjects.

This volume is a collection of articles concerned with the typology of valency and valence change in a large and diversified sample of languages that display ergative alignment in their grammar. The sample of languages represented in these descriptive contributions covers most of the geographical areas and linguistic families in which ergativity has been known to exist jointly with well-developed morphological voice, and some languages belonging to families in which ergativity or voice were not previously recognized or adequately described up to now.

This volume contains 14 descriptive chapters and a collection of 4 transcribed texts in Mursi, a highly endangered language spoken in the Lower Omo Valley in Ethiopia.
