Vernacular in the context of "Southern American English"

Prose is language that follows the natural flow or rhythm of speech, ordinary grammatical structures, or, in writing, typical conventions and formatting. Thus, prose ranges from informal speaking to formal academic writing. Prose differs most notably from poetry, which follows some type of intentional, contrived, artistic structure. Poetic structures vary dramatically by language; in English poetry, language is often organized by a rhythmic metre and a rhyme scheme.

The ordinary conversational language of a region or community, and many other forms and styles of language usage, fall under prose, a label that can describe both speech and writing. In writing, prose is visually formatted differently than poetry. Poetry is traditionally written in verse: a series of lines on a page, parallel to the way that a person would highlight the structure orally if saying the poem aloud; for example, poetry may end with a rhyme at the end of each line, making the entire work more melodious or memorable. Prose uses writing conventions and formatting that may highlight meaning—for instance, the use of a new paragraph for a new speaker in a novel—but does not follow any special rhythmic or other artistic structure.

A natural language or ordinary language is any spoken language or signed language used organically in a human community, first emerging without conscious premeditation and subject to: replication across generations of people in the community, regional expansion or contraction, and gradual internal and structural changes. The vast majority of languages in the world are natural languages. As a category, natural language includes both standard dialects (ones with high social prestige) as well as nonstandard or vernacular dialects. Even an official language with a regulating academy such as Standard French, overseen by the Académie Française, is still classified as a natural language (e.g. in the field of natural language processing), as its prescriptive aspects do not make it regulated enough to be considered a constructed or controlled natural language. Linguists broadly consider writing to be a static visual representation of a particular natural language, though, in many cases in highly literate modern societies, writing itself can also be considered natural language.

Excluded from the definition of natural language are: artificial and constructed languages, such as those developed for works of fiction; languages of formal logic, such as those in computer programming; and non-human communication systems in nature, such as whale vocalizations or honey bees' waggle dance. The academic consensus is that particular key features prevent animal communication systems from being classified as languages at all. Certain human communication or linguistic systems with no native speakers, as sometimes used in cross-cultural contexts, are also not natural languages.

Literary language is the register of a language used when writing in a formal, academic, or particularly polite tone; when speaking or writing in such a tone, it can also be known as formal language. It may be the standardized variety of a language. It can sometimes differ noticeably from the various spoken lects, but the difference between literary and non-literary forms is greater in some languages than in others. If there is a strong divergence between a written form and the spoken vernacular, the language is said to exhibit diglossia.

The understanding of the term differs from one linguistic tradition to another and is dependent on the terminological conventions adopted.

In linguistics, diglossia (/daɪˈɡlɒsiə/ dy-GLOSS-ee-ə, US also /daɪˈɡlɔːsiə/ dy-GLAW-see-ə) is where two dialects or languages are used (in fairly strict compartmentalization) by a single language community. In addition to the community's everyday or vernacular language variety (labeled "L" or "low" variety), a second, highly codified lect (labeled "H" or "high") 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 within the community. 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.

The high variety may be an older stage of the same language (as in medieval Europe, where Latin (H) remained in formal use even as colloquial speech (L) diverged), an unrelated language, or a distinct yet closely related present-day dialect (as in northern India and Pakistan, where Hindustani (L) is used alongside the standard registers of Hindi (H) and Urdu (H); Germany, where Hochdeutsch (H) is used alongside German dialects (L); the Arab world, where Modern Standard Arabic (H) is used alongside other varieties of Arabic (L); and China, where Standard Chinese (H) is used as the official, literary standard and local varieties of Chinese (L) are used in everyday communication); in Dravidian languages, Tamil has the largest diglossia with Literary Tamil (H) used in formal settings and colloquial spoken Tamil (L) used in daily life. Other examples include literary Katharevousa (H) versus spoken Demotic Greek (L); Indonesian, with its bahasa baku (H) and bahasa gaul (L) forms; Standard American English (H) versus African-American Vernacular English or Hawaiian Pidgin (L); and literary (H) versus spoken (L) Welsh.

Demotic Greek (Greek: Δημοτική Γλώσσα, Dimotikí Glóssa, [ðimotiˈci ˈɣlo.sa], lit. 'language of the people') is the standard spoken language of Greece in modern times and, since the resolution of the Greek language question in 1976, the official language of Greece. "Demotic Greek" (with a capital D) contrasts with the conservative Katharevousa, which was used in formal settings, during the same period. In that context, Demotic Greek describes the specific non-standardized vernacular forms of Greek used by the vast majority of Greeks during the 19th and 20th centuries.

As is typical of diglossic situations, Katharevousa and Demotic complemented and influenced each other. Over time, Demotic became standardized. In 1976, it was made the official language of Greece. It continued to evolve and is now called Standard Modern Greek. The term "demotic Greek" (with a minuscule d) also refers to any variety of the Greek language which has evolved naturally from Ancient Greek and is popularly spoken.

Classical Latin is the form of Literary Latin recognized as a literary standard by writers of the late Roman Republic and early Roman Empire. It developed around 75 BC from Old Latin, and developed by the 3rd century AD into Late Latin. In some later periods, the former was regarded as good or proper Latin, while the latter was seen as debased, degenerate, or corrupted. The word Latin is now understood by default to mean "Classical Latin"; for example, modern Latin textbooks almost exclusively teach Classical Latin.

Cicero and his contemporaries of the late republic referred to the Latin language, in contrast to other languages such as Greek, as lingua latina or sermo latinus. They distinguished the common vernacular, however, as Vulgar Latin (sermo vulgaris and sermo vulgi), in contrast to the higher register that they called latinitas, sometimes translated as "Latinity". Latinitas was also called sermo familiaris ("speech of the good families"), sermo urbanus ("speech of the city"), and in rare cases sermo nobilis ("noble speech"). Besides the noun Latinitas, it was referred to with the adverb latine ("in (good) Latin", literally "Latinly") or its comparative latinius ("in better Latin", literally "more Latinly").

Dante Alighieri (Italian: [ˈdante aliˈɡjɛːri]; most likely baptized Durante di Alighiero degli Alighieri; c. May 1265 – September 14, 1321), widely known mononymously as Dante, was an Italian poet, writer, and philosopher. His Divine Comedy, originally called Comedìa (modern Italian: Commedia) and later christened Divina by Giovanni Boccaccio, is widely considered one of the most important poems of the Middle Ages and the greatest literary work in the Italian language.

At a time when Latin was still the dominant language for scholarly and literary writing—and when many Italian poets drew inspiration from French or Provençal traditions—Dante broke with both by writing in the vernacular, specifically his native Tuscan dialect. His De vulgari eloquentia (On Eloquence in the Vernacular) was one of the first scholarly defenses of the vernacular. His use of the Florentine dialect for works such as The New Life (1295) and Divine Comedy helped establish the modern-day standardized Italian language. His work set a precedent that important Italian writers such as Petrarch and Boccaccio would later follow.

A standard language (or standard variety, standard dialect, standardized dialect or simply standard) is any language variety that has undergone substantial codification in its grammar, lexicon, writing system, or other features and that stands out among related varieties in a community as the one with the highest status or prestige. Often, it is the prestige language variety of a whole country.

In linguistics, the process of a variety becoming organized into a standard, for instance by being widely expounded in grammar books or other reference works, and also the process of making people's language usage conform to that standard, is called standardization. Typically, the varieties that undergo standardization are those associated with centres of commerce and government, used frequently by educated people and in news broadcasting, and taught widely in schools and to non-native learners of the language. Within a language community, standardization usually begins with a particular variety being selected (often towards a goal of further linguistic uniformity), accepted by influential people, socially and culturally spread, established in opposition to competitor varieties, maintained, increasingly used in diverse contexts, and assigned a high social status as a result of the variety being linked to the most successful people. As a sociological effect of these processes, most users of a standard dialect—and many users of other dialects of the same language—come to believe that the standard is inherently superior to, or consider it the linguistic baseline against which to judge, the other dialects. However, such beliefs are firmly rooted in social perceptions rather than any objective evaluation. Any varieties that do not carry high social status in a community (and thus may be defined in opposition to standard dialects) are called nonstandard or vernacular dialects.
