Peculiarities of american and british slang: Slang and the Dictionary

Slang consists of the words and expressions that have escaped from the cant, jargon and argot (and to a lesser extent from dialectal, nonstandard, and taboo speech) of specific subgroups of society so that they are known and used by an appreciable percentage of the general population, even though the words and expressions often retain some associations with the subgroups that originally used and popularized them. Thus, slang is a middle ground for words and expressions that have become too popular to be any longer considered as part of the more restricted categories, but that are not yet (and may never become) acceptable or popular enough to be considered informal or standard. (Compare the slang "hooker" and the standard "prostitute.")
