Linguistic geography is an interdisciplinary field that studies the language variation in geographical space. Language is deeply connected to socio-cultural and historical events and is shaped by the geographical dispersion of communities. Synonyms for linguistic geography include dialect geography, geolinguistics, linguistic cartography, and linguistic landscape. Dialect geography highlights the diversity of regional language varieties and their spatial distribution. Geolinguistics emphasizes the geographically-based study of language change, dialect evolution, and patterns of linguistic interaction between different groups. Linguistic cartography focuses on mapping the spatial distribution of various linguistic phenomena, such as language clusters, dialect regions, and language contact zones. Linguistic landscape explores the visual representation of language through analyzing the linguistic signs and symbols in the built environment.
