This atlas maps various time-space dimensions of South Africa’s remarkable linguistic diversity to cast the geography of language within the conceptual framework of geolinguistics. It shows how historical patterns of spatial language preponderance have developed to produce current patterns and allows understanding of the way landscape has become regionally ingrained in the vocabulary of languages. Here language is cast as a barometer of the social dynamics processes of space and place: spatial convergence, regional competition, expansion and dominance, segregation and assimilation, ethnicity, social ecology, language identity, social interaction and migration trends.
