Grammaticalization research looks back on a rich history, but recent empirical findings, as well as new insights from cognitive science and psycholinguistics, entice researchers to reassess and review what we know about the process. This book presents a detailed study of the grammaticalization of motion verbs in the Mayan languages. The focus lies on variation in the parallel grammaticalization of motion verbs into auxiliaries and directionals. It is demonstrated that the genetically related and areally close languages do not always grammaticalize source items in the same way - both from a formal and meaning perspective. The empirical findings suggest that traditional theories on grammaticalization do not capture the complex nature of the phenomenon entirely. Therefore, a Network Approach to grammaticalization is introduced which emphasizes a 'meaning-first' account. The approach seeks to combine the conceptual with the discourse-pragmatic while being firmly grounded in cognitive and psychological facts. New insights into the grammaticalization behavior of the world's languages are offered, while well-established notions and assumptions within the grammaticalization research paradigm are reviewed and challenged.

As a follow-up study to the global comparison of spatial interrogatives (Studia Typologica 20), the present book examines the spatial declarative counterparts which are provided by the expression class of spatial deictic adverbs. In a functionally motivated typological approach, equivalents of Early Modern English here - hither - hence and there - thither - thence are identified across a sample of 250 languages from all macro-areas. These are also quantitatively assessed to extrapolate areal and global trends of coding patterns. The formal relationships between spatial interrogative and spatial declarative paradigms are analyzed with a focus on the syncretism of categories and of individual cells. Qualitative discussions of patterns precede in-depth treatments of problematic cases and other relevant issues related to the research topic. The quantitative results strongly point to areal linguistic trends concerning the distribution of distinct and non-distinct coding of the three spatial relations Place, Goal, and Source. Additional aspects such as quantitative evaluations of constructional complexity are addressed subsequently.
