geographic dialect

Geographic dialects are regional variations of a language, distinguished by differences in grammar, vocabulary, and pronunciation. The study of these variations is called dialectology or linguistic geography.123

Dialect maps and atlases are used to document these differences, showing how features like word usage or pronunciation change across different locations. For example, American English has distinct dialect regions along the Atlantic coast, such as Northern, Midland, and Southern dialects, each with its own subdialects.24

While dialects of the same language are generally mutually intelligible, significant differences can accumulate over distance. Factors like geographic barriers, historical events, and social stratification can influence the development and spread of dialectal features. In modern times, increased mobility and mass communication tend to reduce dialectal differences, often by promoting a standard language.512
