The term dialect can refer to either of two distinctly different types of linguistic phenomena:
Sociolinguistics is the descriptive study of the effect of any or all aspects of society, including cultural norms, expectations, and context, on the way language is used, and society's effect on language. It can overlap with the sociology of language, which focuses on the effect of language on society. Sociolinguistics overlaps considerably with pragmatics and is closely related to linguistic anthropology.
Linguistic prescription, or prescriptive grammar, is the establishment of rules defining preferred usage of language. These rules may address such linguistic aspects as spelling, pronunciation, vocabulary, syntax, and semantics. Sometimes informed by linguistic purism, such normative practices often suggest that some usages are incorrect, inconsistent, illogical, lack communicative effect, or are of low aesthetic value, even in cases where such usage is more common than the prescribed usage. They may also include judgments on socially proper and politically correct language use.
In sociolinguistics, a variety, also called an isolect or lect, is a specific form of a language or language cluster. This may include languages, dialects, registers, styles, or other forms of language, as well as a standard variety. The use of the word "variety" to refer to the different forms avoids the use of the term language, which many people associate only with the standard language, and the term dialect, which is often associated with non-standard varieties thought of as less prestigious or "correct" than the standard. Linguists speak of both standard and non-standard (vernacular) varieties. "Lect" avoids the problem in ambiguous cases of deciding whether two varieties are distinct languages or dialects of a single language.
In sociolinguistics, an accent is a way of pronouncing a language that is distinctive to a country, area, social class, or individual. An accent may be identified with the locality in which its speakers reside, the socioeconomic status of its speakers, their ethnicity, their caste or social class, or influence from their first language.
In sociolinguistics, hypercorrection is non-standard use of language that results from the over-application of a perceived rule of language-usage prescription. A speaker or writer who produces a hypercorrection generally believes through a misunderstanding of such rules that the form is more "correct", standard, or otherwise preferable, often combined with a desire to appear formal or educated.
In linguistics, diglossia is a situation in which two dialects or languages are used by a single language community. In addition to the community's everyday or vernacular language variety, a second, highly codified lect is used in certain situations such as literature, formal education, or other specific settings, but not used normally for ordinary conversation. The H variety may have no native speakers but various degrees of fluency of the low speakers. In cases of three dialects, the term triglossia is used. When referring to two writing systems coexisting for a single language, the term digraphia is used.
In sociolinguistics, an abstand language is a language variety or cluster of varieties with significant linguistic distance from all others, while an ausbau language is a standard variety, possibly with related dependent varieties. Heinz Kloss introduced these terms in 1952 to denote two separate and largely independent sets of criteria for recognizing a "language":
In sociolinguistics, prestige 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. 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.
Einar Ingvald Haugen was an American linguist, writer, and professor at University of Wisconsin–Madison and Harvard University.
Linguistic purism or linguistic protectionism is the prescriptive practice of defining or recognizing one variety of a language as being purer or of intrinsically higher quality than other varieties. Linguistic purism was institutionalized through language academies, and their decisions often have the force of law.
Language politics is the way language and linguistic differences between peoples are dealt with in the political arena. This could manifest as government recognition, as well as how language is treated in official capacities.
Language ideology is, within anthropology, sociolinguistics, and cross-cultural studies, any set of beliefs about languages as they are used in their social worlds. Language ideologies are conceptualizations about languages, speakers, and discursive practices. Like other kinds of ideologies, language ideologies are influenced by political and moral interests, and they are shaped in a cultural setting. When recognized and explored, language ideologies expose how the speakers' linguistic beliefs are linked to the broader social and cultural systems to which they belong, illustrating how the systems beget such beliefs. By doing so, language ideologies link implicit and explicit assumptions about a language or language in general to their social experience as well as their political and economic interests.
A diaphoneme is an abstract phonological unit that identifies a correspondence between related sounds of two or more varieties of a language or language cluster. For example, some English varieties contrast the vowel of late with that of wait or eight. Other English varieties contrast the vowel of late or wait with that of eight. This non-overlapping pair of phonemes from two different varieties can be reconciled by positing three different diaphonemes: A first diaphoneme for words like late, a second diaphoneme for words like wait, and a third diaphoneme for words like eight.
Linguistic insecurity comprises feelings of anxiety, self-consciousness, or lack of confidence in the mind of a speaker surrounding their use of language. Often, this anxiety comes from speakers' belief that their speech does not conform to the perceived standard and/or the style of language expected by the speakers' interlocutor(s). Linguistic insecurity is situationally induced and is often based on a feeling of inadequacy regarding personal performance in certain contexts, rather than a fixed attribute of an individual. This insecurity can lead to stylistic, and phonetic shifts away from an affected speaker's default speech variety; these shifts may be performed consciously on the part of the speaker, or may be reflective of an unconscious effort to conform to a more prestigious or context-appropriate variety or style of speech. Linguistic insecurity is linked to the perception of speech varieties in any community, and so may vary based on socioeconomic class and gender. It is also especially pertinent in multilingual societies.
Variation is a characteristic of language: there is more than one way of saying the same thing. Speakers may vary pronunciation (accent), word choice (lexicon), or morphology and syntax. But while the diversity of variation is great, there seem to be boundaries on variation – speakers do not generally make drastic alterations in sentence word order or use novel sounds that are completely foreign to the language being spoken. Linguistic variation does not equate with language ungrammaticality, but speakers are still sensitive to what is and is not possible in their native lect.
African-American Vernacular English (AAVE) has been the center of controversy about the education of African-American youths, the role AAVE should play in public schools and education, and its place in broader society.
Linguistic discrimination is unfair treatment of people which is based on their use of language and the characteristics of their speech, including their first language, their accent, the perceived size of their vocabulary, their modality, and their syntax. For example, an Occitan speaker in France will probably be treated differently from a French speaker. Based on a difference in use of language, a person may automatically form judgments about another person's wealth, education, social status, character or other traits, which may lead to discrimination.
The gender paradox is a sociolinguistic phenomenon first observed by William Labov, in which "Women conform more closely than men to sociolinguistic norms that are overtly prescribed, but conform less than men when they are not." Specifically, the "paradox" arises from sociolinguistic data showing that women are more likely to use prestige forms and avoid stigmatized variants than men for a majority of linguistic variables, but that they are also more likely to lead language change by using innovative forms of variables.
In sociolinguistics, covert prestige is a type of scenario in which nonstandard languages or dialects are regarded to be of high linguistic prestige by members of a speech community. This is in contrast to the typical case of linguistic prestige, wherein only the standard varieties of a speech community are considered prestigious.
