The study of dialects—the different ways people speak in various regions, social groups, and time periods.
From Greek dialektos (conversation, dialect, local speech) + -logia (study of, discourse). The term emerged in the 19th century as linguistics became a formal academic field focused on understanding language variation.
Dialectology reveals that nobody speaks 'wrong'—they just speak differently, and these differences tell stories about migration, trade, cultural mixing, and how communities developed unique identities through language.
