2. See speech. 4, 9. tongue; terminology; lingo, lingua franca. Language, dialect, jargon, vernacular refer to linguistic configurations of vocabulary, syntax, phonology, and usage that are characteristic of communities of various sizes and types. Language is a broad term applied to the overall linguistic configurations that allow a particular people to communicate: the English language; the French language. Dialect is applied to certain forms or varieties of a language, often those that provincial communities or special groups retain (or develop) even after a standard has been established: Scottish dialect; regional dialect; Southern dialect. A jargon is either an artificial linguistic configuration used by a particular (usually occupational) group within a community or a special configuration created for communication in a particular business or trade or for communication between members of groups that speak different languages: computer jargon; the Chinook jargon. A vernacular is the authentic natural pattern–the ordinary speech–of a given language, now usually on the informal level. It is at once congruent with and, in relatively small ways, distinguished from the standard language in syntax, vocabulary, usage, and pronunciation. It is used by persons indigenous to a certain community, large or small.
