in speech across a wide range of contexts, while slang tends to be perceived as infelicitous in many common communicative situations. Jargon refers to language used by personnel in a particular field, or language used to represent specific terms within a field to those with a particular interest. Although jargon and slang can both be used to exclude non-group members from the conversation, the purpose of jargon is said to be optimizing conversation using terms that imply technical understanding. On the other hand, slang tends to emphasize social and contextual understanding. While colloquialisms and jargon may seem like slang because they reference a particular group, they do not necessarily fit the same definition, because they do not represent a particular effort to replace the general lexicon of a standard language. Colloquialisms are considered more acceptable and more expected in standard usage than slang is, and jargon is often created to talk about aspects of a particular field that are not accounted for in the general lexicon. However, this differentiation is not consistently applied by linguists; the terms "slang" and "jargon" are sometimes treated as synonymous, and the scope of "jargon" is at times extended to mean all forms of socially-restricted language. It is often difficult to differentiate slang from colloquialisms and even high-register lexicon, because slang generally becomes accepted into common vocabulary over time. Words such as "spurious" and "strenuous" were once perceived as slang, though they are now considered general, even high-register words. The literature on slang even discusses mainstream acknowledgment of a slang term as changing its status as true slang, because it has been accepted by the media and is thus no longer the special insider speech of a particular group. For example, Black American Music uses a lot of slang based on nationality and origin. The use of slang is a combinations of slurring and slurping words as a result. Nevertheless, a general test for whether a word is a slang word or not is whether it would be acceptable in an academic or legal setting, as both are arenas in which standard lexicon is considered necessary and/or whether the term has been entered in the Oxford English Dictionary, which some scholars claim changes its status as slang.
