Dialectology is the study of regional language variations, focusing on how dialects differ in pronunciation, vocabulary, and grammar. This field examines the social and geographical factors that influence these variations, helping linguists understand how language evolves over time. Researchers in dialectology often conduct surveys and interviews to collect data from speakers in different areas. They may analyze dialects within specific regions, such as the United States or the United Kingdom, to identify unique linguistic features. This research contributes to our understanding of language diversity and the cultural identities tied to different dialects.
