Grammaticalization from a Typological Perspective [PDF ebook] 

This volume explores the way in which grammaticalization processes – whereby lexical words eventually become markers of grammatical categories – converge and differ across various types of language. While grammaticalization at its core is a unidirectional phenomenon, in which the same pathways of change are replicated across languages, certain language types and language areas have distinct preferences with respect to what they grammaticalize and how. Previous workhas principally addressed this question with specific reference to languages of Southeast and East Asia that do not seem to grammaticalize paradigms of categories in the same manner as Indo-European languages, or form extensive grammaticalization chains. This volume takes a broader approach andproceeds systematically area by area: specialists in the field address the processes of grammaticalization in languages of Africa, Europe, Asia and the Pacific, and the Americas, and in creole languages. The studies reveal a number of unique pathways of grammaticalization in each language area, as well as identifying the universal shared features of the phenomenon.
