While the comparative method is concerned with regularities in phonological
change, grammaticalization theory deals with regularities of grammatical
change. In an A-Z format, this book summarizes the most salient
generalizations that have been made on the unidirectional change of
grammatical forms and constructions. The product of ten years of research,
World Lexicon of Grammaticalization provides the reader with the tools to
show how different grammatical meanings can be related to one another in a
principled way, how to deal with issues such as polysemy and heterosemy, or
why certain linguistic forms have simultaneous lexical and grammatical
functions. It covers several hundred grammaticalization processes, in each
case offering definitions of lexical concepts, suitable examples from a
variety of languages, and references to the relevant research literature.
Indices organized by source and target concepts allow for flexible use, and
the findings delineated in the book are relevant to students of language
across theoretical boundaries.
