Offers perspectives on "shared grammaticalization", a state whereby two or more languages have the source and the target of a grammaticalization process in common. This book intends to put this situation right by approaching shared grammaticalization from an integrated perspective, including areal and genealogical and universal motivations.

The volume stands out because of the vast amount of empirical data gathered and presented, not only from the Transeurasian languages, but from European and Amazonian languages as well. Additionally, many different linguistic areas are represented within the volume: morphology (articles, verbs, personal pronouns, allocutivity markers), lexicology (suffixes and prefixes), semantics (scalar additive operators), phonology (fricatives, voicing) and syntax (insubordination). [...] The methodology and theoretical aspects brought into light are of great value for those researchers who wish to start or continue their own research in the field of grammaticalization, regardless of the languages or linguistic categories in question.
