Language geography

Language geography is the branch of human geography that studies the geographic distribution of language or its constituent elements. There are two principal fields of study within the geography of language: the "geography of languages", which deals with the distribution through history and space of languages, and "linguistic geography", which deals with regional linguistic variations within languages. Various other terms and subdisciplines have been suggested, including: a division within the examination of linguistic geography separating the studies of change over time and space; 'geolinguistics', a study within the geography of language concerned with 'the analysis of the distribution patterns and spatial structures of languages in contact', but none gained much currency.
