sociolect

noun

1. The variant of language used by a social group such as a socioeconomic class, an ethnic group, an age group, etc.

   “The French literary critic Roland Barthes has paid special attention to the relationship between the individual language ("idiolect") and the language of a collective of speech ("sociolect"). Public life is characterized by "social multilingualism." There are a number of languages, such as the language of the church, the language of the prison, the language of the children, the language of the ruling elite, and other "social languages."”

   “[…] I believe that it is mistaken to maintain that the language of ideology is a discrete ‘sociolect’, a sort of meta-language which draws upon but remains distinct from the language of everyday life.”

   “This paper uses sociolect as a cover term for slang, technical jargon (professionalisms), and argot. From the point of view of its secret nature, two kinds of sociolects are distinguished: slang and technical jargon on the one hand, and argot on the other, with the difference being in the presence or lack of an intention of secrecy.”
