regional dialect

A dialect is a variety of a language that indicates a person's geographic origin or social background. Dialects are distinguished by variations in vocabulary, grammar, and pronunciation. While dialects of the same language are generally mutually intelligible, the exact distinction between a dialect and a separate language can be arbitrary.123

Dialectology is the study of these variations, often mapping their distribution within a language. Regional dialects, like those found across the United States (e.g., Northern, Midland, Southern), are shaped by geographic isolation and historical settlement patterns. Social dialects, on the other hand, are influenced by factors like social class and education.241

Modern influences such as mass media and increased mobility tend to reduce dialectal differences, often leading to the adoption of a standard language. However, immigrant groups and regional pockets can maintain distinct dialectal features.14
