Linguistic variation is a topic of ongoing interest to the field. Its description and its explanations continue to intrigue scholars from many different backgrounds. By taking a deliberately broad perspective on the matter, covering not only crosslinguistic and diachronic but also intralinguistic and interspeaker variation and examining phenomena ranging from negation over connectives to definite articles in well- and lesser-known languages, the volume furthers our understanding of variation in general. The papers offer new insights into, among other things, the theoretical notion of comparative concepts, the social or mental nature of language structure, the areal factor in lexical typology and the diachronic implications of semantic maps. The collection will thus be of relevance to typologists and historical linguists, as well as to people studying variation within the areas of cognitive and functional linguistics.

This compilation of invited contributions, gathering an international collection of cognitive and functional linguists, offers an outline of original empirical work carried out in grounding theory. Grounding is a central notion in cognitive grammar that addresses the linking of semantic content to contextual factors that constitute the subjective ground (or situation of speech). The volume illustrates a growing concern with the application of cognitive grammar to constructions establishing deixis and reference. It proposes a double focus on nominal and clausal grounding, as well as on ways of integrating analyses across these domains.
