This volume examines the way human beings experience space and the way it is encoded grammatically in language. Basing her observations on 26 unrelated languages, the author centers the research on the encoding and expression of spatial relations around the emergence and evolution of spatial "grams," and the semantic and morphosyntactic characteristics of two types of spatial grams, which are shown to be similar for all languages, not only for the expression of spatial relations, but also for temporal and other non-spatial relations. Motivation for these similarities may lie in the way we, as human beings, experience the world, which is constrained by our physical configuration and neurophysiological apparatus, as well as our individual cultures.
