sociolect

noun

Etymology: From socio- + -lect, by analogy with dialect, idiolect, etc.

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.”
