Prolanguage

In conlinguistics, a prolanguage (Lat: prolinguāticum) is a pro-form that substitutes one language for another, usually in a work of fiction. The replaced language is called the antecedent of the prolanguage.

For example, in J. R. R. Tolkien's Lord of the Rings we hear about certain languages: Common Speech, Rohirric and the Hobbits' dialect of the Common Speech. Yet we only rarely glimpse the conlangs themselves, the most famous being Quenya, Sindarin and the Black Speech. When it comes to the Common Speech -- the language all the characters speak in during the course of the narrative -- we read their words in English (or whatever language the novels have been translated into). It is this use of, in this instance, the English language as a stand-in for the Common Speech that exemplifies the concept of the prolanguage.

As a literary device, examples abound, from Tolkien's Lord of the Rings to Howard's Conan to Jacques's Redwall series all of which use English . This last author makes a very consisted use of dialects and accents of English to stand as prolanguages for the true speech of his animal characters. Only rarely do we see any devised languages or words, the otters' language being a good example.
