Dialect
Dialect (from Latin dialectus, dialectos, from the Ancient Greek word διάλεκτος, diálektos 'discourse', from διά, diá 'through' and λέγω, légō 'I speak') refers to two distinctly different types of linguistic relationships. The more common usage of the term refers to a variety of a language that is a characteristic of a particular group of the language's speakers. The dialects or varieties of a particular language are closely related and, despite their differences, are most often largely mutually intelligible, especially if geographically close to one another in a dialect continuum. The term is applied most often to regional speech patterns, but a dialect may also be defined by other factors, such as social class or ethnicity. A dialect that is associated with a particular social class can be termed a sociolect, a dialect that is associated with a particular ethnic group can be termed an ethnolect, and a geographical/regional dialect may be termed a regiolect (alternative terms include 'regionalect', 'geolect', and 'topolect').
