Dialect in the context of Masurian dialects

Modern Greek (endonym: Νέα Ελληνικά, Néa Elliniká [ˈne.a eliniˈka] or Κοινή Νεοελληνική Γλώσσα, Kiní Neoellinikí Glóssa), generally referred to by speakers simply as Greek (Ελληνικά, Elliniká), refers collectively to the dialects of the Greek language spoken in the modern era, including the official standardized form of the language sometimes referred to as Standard Modern Greek. The end of the Medieval Greek period and the beginning of Modern Greek is often symbolically assigned to the fall of the Byzantine Empire in 1453, even though that date marks no clear linguistic boundary and many characteristic features of the modern language arose centuries earlier, having begun around the fourth century AD.

During most of the Modern Greek period, the language existed in a situation of diglossia, with regional spoken dialects existing side by side with learned, more archaic written forms, as with the vernacular and learned varieties (Dimotiki and Katharevousa) that co-existed in Greece throughout much of the 19th and 20th centuries.

Pronunciation is the way in which a word or a language is spoken.

This may refer to generally agreed-upon sequences of sounds used in speaking a given word or all language in a specific dialect—"correct" or "standard" pronunciation—or simply the way a particular individual speaks a word or language.

The linguistic varieties of Modern Greek can be classified along two principal dimensions. First, there is a long tradition of sociolectal variation between the natural, popular spoken language on the one hand and archaizing, learned written forms on the other. Second, there is regional variation between dialects. The competition between the popular and the learned registers (see Diglossia) culminated in the struggle between Dimotiki and Katharevousa during the 19th and 20th centuries. As for regional dialects, variation within the bulk of dialects of present-day Greece is not particularly strong, except for a number of outlying, highly divergent dialects spoken by isolated communities.

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.

Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.

Estimates of the number of human languages in the world vary between 5,000 and 7,000. Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whistling, signing, or braille. In other words, human language is modality-independent, but written or signed language is the way to inscribe or encode the natural human speech or gestures.

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).

The Romani people (/ˈroʊməni/ or /ˈrɒməni/), also known as the Roma (sg.: Rom) or Romanies (sg.: Romany), are an Indo-Aryan ethnic group who traditionally lived a nomadic lifestyle. Although they are widely dispersed, their most concentrated populations are believed to be in Romania, Bulgaria, Hungary, Serbia, and Slovakia. In the English language, Romani people have long been known by the exonym Gypsies or Gipsies and this remains the most common English term for the group. Some Roma use and embrace this term while others consider it to be derogatory or an ethnic slur.

Romani culture has been influenced by their time spent under various reigns and empires, notably the Byzantine and Ottoman empires. The Romani language is an Indo-Aryan language with strong Persian, Armenian, Byzantine Greek and South Slavic influence. It is divided into several dialects, which together are estimated to have over 2 million speakers. Many Roma are native speakers of the dominant language in their country of residence, or else of mixed languages that combine the dominant language with a dialect of Romani in varieties sometimes called para-Romani.

Chinese (spoken: simplified Chinese: 汉语; traditional Chinese: 漢語; pinyin: Hànyǔ, written: 中文; Zhōngwén) is an umbrella term for Sinitic languages in the Sino-Tibetan language family, widely recognized as a group of language varieties, spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in China, as well as by various communities of the Chinese diaspora. Approximately 1.39 billion people, or 17% of the global population, speak one of the Chinese languages as their first language.

The Chinese languages form the Sinitic branch of the Sino-Tibetan language family. The Chinese government considers the spoken varieties of the Chinese languages dialects of a single language. However, their lack of mutual intelligibility means they are considered to be separate languages in a family by linguists. Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese, of which the most spoken by far is Mandarin with 66%, or around 800 million speakers, followed by Min (75 million, e.g., Southern Min), Wu (74 million, e.g., Shanghainese), and Yue (68 million, e.g., Cantonese). These branches are unintelligible to each other, and many of their subgroups are unintelligible with the other varieties within the same branch (e.g., Southern Min). There are, however, transitional areas where varieties from different branches share enough features for some limited intelligibility, including New Xiang with Southwestern Mandarin, Xuanzhou Wu Chinese with Lower Yangtze Mandarin, Jin with Central Plains Mandarin and certain divergent dialects of Hakka with Gan. All varieties of Chinese are tonal at least to some degree, and are largely analytic.

This is a list of languages by total number of speakers.

It is difficult to define what constitutes a language as opposed to a dialect. For example, while Arabic is sometimes considered a single language centred on Modern Standard Arabic, other authors consider its mutually unintelligible varieties separate languages. Similarly, Chinese is sometimes viewed as a single language because of a shared culture and common literary language, but sometimes considered multiple languages. Conversely, colloquial registers of Hindi and Urdu are almost completely mutually intelligible and are sometimes classified as one language, Hindustani. Rankings of languages should therefore be used with caution, as it is not possible to devise a coherent set of linguistic criteria for distinguishing languages in a dialect continuum.

Macedonian (/ˌmæsɪˈdoʊniən/ MASS-ih-DOH-nee-ən; македонски јазик, translit. makedonski jazik, pronounced [maˈkɛdɔnski ˈjazik] ) is an Eastern South Slavic language. It is part of the Indo-European language family, and is one of the Slavic languages, which are part of a larger Balto-Slavic branch. Spoken as a first language by around 1.7 million people, it serves as the official language of North Macedonia. Most speakers can be found in the country and its diaspora, with a smaller number of speakers throughout the transnational region of Macedonia. Macedonian is also a recognized minority language in parts of Albania, Bosnia and Herzegovina, Romania, and Serbia and it is spoken by expatriate communities predominantly in Australia, Canada, and the United States.

Macedonian developed out of the western dialects of the Eastern South Slavic dialect continuum, whose earliest recorded form is Old Church Slavonic. During much of its history, this dialect continuum was called "Bulgarian", although in the late 19th century, its western dialects came to be known separately as "Macedonian". Standard Macedonian was codified in 1945 and has developed modern literature since. As it is part of a dialect continuum with other South Slavic languages, Macedonian has a high degree of mutual intelligibility with Bulgarian and varieties of Serbo-Croatian.

A national language is a language (or language variant, e.g. dialect) that has some connection—de facto or de jure—with a nation. The term is applied quite differently in various contexts. One or more languages spoken as first languages in the territory of a country may be referred to informally or designated in legislation as national languages of the country. National languages are mentioned in over 150 world constitutions.

C.M.B. Brann, with particular reference to India, suggests that there are "four quite distinctive meanings" for national language in a polity:

Sludge (possibly from Middle English slutch 'mud, mire', or some dialect related to slush) is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems. It can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage sludge from wastewater treatment processes or as fecal sludge from pit latrines and septic tanks. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this soupy material usually contains significant quantities of interstitial water (between the solid particles). Sludge can consist of a variety of particles, such as animal manure.

Industrial wastewater treatment plants produce solids that are also referred to as sludge. This can be generated from biological or physical-chemical processes.

Coptic (Bohairic Coptic: ϯⲙⲉⲧⲣⲉⲙⲛ̀ⲭⲏⲙⲓ, romanized: Timetremənkʰēmi) is a dormant Afroasiatic language. It is a group of closely related Egyptian dialects, representing the most recent developments of the Egyptian language, and historically spoken by the Copts, starting from the third century AD in Roman Egypt. Coptic was supplanted by Arabic as the primary spoken language of Egypt following the Arab conquest of Egypt and was slowly replaced over the centuries.

Coptic has no modern-day native speakers, and no fluent speakers apart from a number of priests, although it remains in daily use as the liturgical language of the Coptic Orthodox Church and of the Coptic Catholic Church. It is written with the Coptic alphabet, a modified form of the Greek alphabet with seven additional letters borrowed from the Demotic Egyptian script.

Georgian (ქართული ენა, kartuli ena, pronounced [ˈkʰäɾt̪ʰuli ˈe̞n̪ä]) is the most widely spoken Kartvelian language. It is the official language of Georgia and the native or primary language of 88% of its population. It also serves as the literary language or lingua franca for speakers of related languages. Its speakers today amount to approximately 3.8 million. Georgian is written with its own unique Georgian scripts, alphabetical systems of unclear origin.

Georgian is most closely related to the Zan languages (Megrelian and Laz) and more distantly to Svan. Georgian has various dialects, with standard Georgian based on the Kartlian dialect, and all dialects are mutually intelligible. The history of Georgian spans from Early Old Georgian in the 5th century, to Modern Georgian today. Its development as a written language began with the Christianization of Georgia in the 4th century.

Adyghe (/ˈædɪɡeɪ/ or /ˌɑːdɪˈɡeɪ/; also known as West Circassian) is a Northwest Caucasian language spoken by the western subgroups of Circassians. It is spoken mainly in Russia, as well as in Turkey, Jordan, Syria, Iraq and Israel, where Circassians settled after the Circassian genocide (c. 1864–1870) by the Russian Empire. It is closely related to the Kabardian (East Circassian) language, though some reject the distinction between the two languages in favor of both being dialects of a unitary Circassian language.

The literary standard of Adyghe is based on its Temirgoy dialect. Adyghe and Russian are the two official languages of the Republic of Adygea in the Russian Federation.

Varieties of Arabic (or dialects or vernaculars) are the linguistic systems that Arabic speakers speak natively. Arabic is a Semitic language within the Afroasiatic family that originated in the Arabian Peninsula. There are considerable variations from region to region, with degrees of mutual intelligibility that are often related to geographical distance and some that are mutually unintelligible. Many aspects of the variability attested to in these modern variants can be found in the ancient Arabic dialects in the peninsula. Likewise, many of the features that characterize (or distinguish) the various modern variants can be attributed to the original settler dialects as well as local native languages and dialects. Some organizations, such as SIL International, consider these approximately 30 different varieties to be separate languages, while others, such as the Library of Congress, consider them all to be dialects of Arabic.

In terms of sociolinguistics, a major distinction exists between the formal standardized language, found mostly in writing or in prepared speech, and the widely diverging vernaculars, used for everyday speaking situations. The latter vary from country to country, from speaker to speaker (according to personal preferences, education and culture), and depending on the topic and situation. In other words, Arabic in its natural environment usually occurs in a situation of diglossia, which means that its native speakers often learn and use two linguistic forms substantially different from each other, the Modern Standard Arabic (MSA) as the official language and a local colloquial variety (called العامية, al-ʿāmmiyya in many Arab countries, meaning "slang" or "colloquial"; or called الدارجة, ad-dārija, meaning "common or everyday language" in the Maghreb), in different aspects of their lives.

In linguistics, a koine or koiné language or dialect (pronounced /ˈkɔɪ.neɪ/, KOY-nay; from Ancient Greek κοινή 'common') is a standard or common dialect that has arisen as a result of the contact, mixing, and often simplification of two or more mutually intelligible varieties of the same language.

As speakers already understood one another before the advent of the koiné, the process of koineization is not as drastic as pidginization and creolization. Unlike pidginization and creolization, there is often no prestige dialect target involved in koineization.
