Covert prestige in the context of "Prestige language"

Prestige in sociolinguistics is the level of regard normally accorded a specific language or dialect within a speech community, relative to other languages or dialects. Prestige varieties are language or dialect families which are generally considered by a society to be the most "correct" or otherwise superior. In many cases, they are the standard form of the language, though there are exceptions, particularly in situations of covert prestige (where a non-standard dialect is highly valued). In addition to dialects and languages, prestige is also applied to smaller linguistic features, such as the pronunciation or usage of words or grammatical constructs, which may not be distinctive enough to constitute a separate dialect. The concept of prestige provides one explanation for the phenomenon of variation in form among speakers of a language or languages.

The presence of prestige dialects is a result of the relationship between the prestige of a group of people and the language that they use. Generally, the language or variety that is regarded as more prestigious in that community is the one used by the more prestigious group. The level of prestige a group has can also influence whether the language that they speak is considered its own language or a dialect (implying that it does not have enough prestige to be considered its own language).
