Dialect continuum in the context of Franconian (linguistics)

American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the U.S. and is an official language in 32 of the 50 U.S. states. It is the de facto common language used in government, education, and commerce in all 50 states, the District of Columbia, and in all territories except Puerto Rico. De jure, there is no official language in the U.S. at the federal level, as there is no federal law designating any language to be official. However, Executive Order 14224 of 2025 declared English to be the official language of the U.S., and English is recognized as such by federal agencies. Since the late 20th century, American English has become the most influential form of English worldwide.

Varieties of American English include many patterns of pronunciation, vocabulary, grammar, and particularly spelling that are unified nationwide but distinct from other forms of English around the world. Any American or Canadian accent perceived as lacking noticeably local, ethnic, or cultural markers is known in linguistics as General American; it covers a fairly uniform accent continuum native to certain regions of the U.S. but especially associated with broadcast mass media and highly educated speech. However, historical and present linguistic evidence does not support the notion of there being one single mainstream American accent. The sound of American English continues to evolve, with some local accents disappearing, but several larger regional accents having emerged in the 20th century.

The Turkic languages are a language family of more than 35 documented languages spoken by the Turkic peoples of Eurasia, from Eastern Europe and Southern Europe to Central Asia, East Asia, North Asia (Siberia), and West Asia. The Turkic languages originated in a region of East Asia spanning from Mongolia to Northwest China, where Proto-Turkic is thought to have been spoken, and from where they expanded to Central Asia and farther west during the first millennium. They are characterized as a dialect continuum.

Turkic languages are spoken by some 200 million people. The Turkic language with the greatest number of speakers is Turkish, spoken mainly in Anatolia and the Balkans; its native speakers account for about 38% of all Turkic speakers, followed by Uzbek.

The Osco-Umbrian, Sabellic or Sabellian languages are an extinct group of Italic languages, the Indo-European languages that were spoken in central and southern Italy by the Osco-Umbrians before being replaced by Latin, as the power of ancient Rome expanded. Their written attestations developed from the middle of the 1st millennium BC to the early centuries of the 1st millennium AD. There is one text of about 4,000 words in Umbrian, but otherwise the languages are known almost exclusively from inscriptions, principally of Oscan and Umbrian, but there are also some Osco-Umbrian loanwords in Latin. Besides the two major branches of Oscan and Umbrian (and their dialects), South Picene may represent a third branch of Sabellic. The whole linguistic Sabellic area, however, might be considered a dialect continuum. Paucity of evidence from most of the "minor dialects" contributes to the difficulty of making these determinations.

The langues d'oïl  are a dialect continuum that includes standard French and its closest relatives historically spoken in the northern half of France, southern Belgium, and the Channel Islands. They belong to the larger category of Gallo-Romance languages, which also include the historical languages of east-central France and western Switzerland, southern France, portions of northern Italy, the Val d'Aran in Spain, and under certain acceptations those of Catalonia.

Linguists divide the Romance languages of France, and especially of Medieval France, into two main geographical subgroups: the langues d'oïl to the north, and the langues d'oc in the southern half of France. Both groups are named after the word for yes in their recent ancestral languages. The most common modern langue d'oïl is standard French, in which the ancestral oïl has become oui.

Francien (French pronunciation: [fʁɑ̃sjɛ̃]), also anglicized as Francian (/ˈfrænsiən/), is a 19th-century term in linguistics that was applied to the French dialect that was spoken during the Middle Ages in the regions of Île-de-France (with Paris at its centre), Orléanais, as well as Touraine, Berry, and Bourbonnais before the establishment of the French language as a standard language.

According to one theory of the development of French, Francien was chosen out of all the competing oïl languages as an official language (Norman and Picard being the main competitors in the medieval period). The theory currently prevailing, however, is that Francien was one of the dialects in the dialect continuum on top of which an administrative language, untrammeled by perceived regionalisms, was imposed as a compromise means of communication and record to replace Latin.

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

All such rankings of human languages ranked by their number of native speakers should be used with caution, because it is not possible to devise a coherent set of linguistic criteria for distinguishing languages in a dialect continuum. For example, a language is often defined as a set of mutually intelligible varieties, but independent national standard languages may be considered separate languages even though they are largely mutually intelligible, as in the case of Danish and Norwegian. Conversely, many commonly accepted languages, including German, Italian, and English, encompass varieties that are not mutually intelligible. 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. It is also common to describe various Chinese dialect groups, such as Mandarin, Wu, and Yue, as languages, even though each of these groups contains many mutually unintelligible varieties.

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.

Bulgarian is an Eastern South Slavic language spoken in Southeast Europe, primarily in Bulgaria. It is the language of the Bulgarians.

Along with the closely related Macedonian language (collectively forming the East South Slavic languages), it is a member of the Balkan sprachbund and South Slavic dialect continuum of the Indo-European language family. The two languages have several characteristics that set them apart from all other Slavic languages, including the elimination of case declension, the development of a suffixed definite article, and the lack of a verb infinitive. They retain and have further developed the Proto-Slavic verb system (albeit analytically). One such major development is the innovation of evidential verb forms to encode for the source of information: witnessed, inferred, or reported.

Serbo-Croatian, also known as Bosnian-Croatian-Montenegrin-Serbian (BCMS), is a South Slavic language and the primary language of Serbia, Croatia, Bosnia and Herzegovina, and Montenegro. It is a pluricentric language with four mutually intelligible standard varieties, namely Serbian, Croatian, Bosnian, and Montenegrin.

South Slavic languages historically formed a dialect continuum. The region's turbulent history, particularly due to the expansion of the Ottoman Empire, led to a complex dialectal and religious mosaic. Due to population migrations, Shtokavian became the most widespread supradialect in the western Balkans, encroaching westward into the area previously dominated by Chakavian and Kajkavian. Bosniaks, Croats, and Serbs differ in religion and were historically often part of different cultural spheres, although large portions of these populations lived side by side under foreign rule. During that period, the language was referred to by various names, such as "Slavic" in general, or "Serbian", "Croatian" or "Bosnian" in particular. In a classicizing manner, it was also referred to as "Illyrian".

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.

Kurdish (Kurdî, کوردی, pronounced [kʊrdiː] ) is a Northwestern Iranian language or group of languages spoken by Kurds in the region of Kurdistan, namely in southeast Turkey, northern Iraq, northwest Iran, and northern Syria. It is also spoken in northeast Iran, as well as in certain areas of Armenia and Azerbaijan.

Kurdish varieties constitute a dialect continuum, with some mutually unintelligible varieties, and collectively have 26 million native speakers. The main varieties of Kurdish are Kurmanji, Sorani, and Southern Kurdish (Xwarîn). The majority of the Kurds speak Kurmanji, and most Kurdish texts are written in Kurmanji and Sorani. Kurmanji is written in the Hawar alphabet, a derivation of the Latin script, and Sorani is written in the Sorani alphabet, a derivation of the Arabic script.

Scotland is a country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent islands, principally in the archipelagos of the Hebrides and the Northern Isles. In 2022, the country's population was about 5.4 million. Its capital city is Edinburgh, whilst Glasgow is the largest city and the most populous of the cities of Scotland. To the south-east, Scotland has its only land border, which is 96 miles (154 km) long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The legislature, the Scottish Parliament, elects 129 members to represent 73 constituencies across the country. The Scottish Government is the executive arm of the devolved government, headed by the first minister, who chairs the cabinet and is responsible for government policy and international engagement.

The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of England and Ireland, forming a personal union of the three kingdoms. On 1 May 1707, Scotland and England combined to create the new Kingdom of Great Britain, with the Parliament of Scotland subsumed into the Parliament of Great Britain. In 1999, a Scottish Parliament was re-established, and has devolved authority over many areas of domestic policy. The country has its own distinct legal system, education system and religious history, which have all contributed to the continuation of Scottish culture and national identity. Scottish English and Scots are the most widely spoken languages in the country, existing on a dialect continuum with each other. Scottish Gaelic speakers can be found all over Scotland, but the language is largely spoken natively by communities within the Hebrides; Gaelic speakers now constitute less than 2% of the total population, although state-sponsored revitalisation attempts have led to a growing community of second language speakers.

Norwegian (endonym: norsk [ˈnɔʂːk] , norsk språk [ˈnɔʂːk sproːk]) is a North Germanic language from the Indo-European language family spoken mainly in Norway, where it is an official language. Along with Swedish and Danish, Norwegian forms a dialect continuum of more or less mutually intelligible local and regional varieties; some Norwegian and Swedish dialects, in particular, are very close. These Scandinavian languages, together with Faroese and Icelandic as well as some extinct languages, constitute the North Germanic languages. Faroese and Icelandic are not mutually intelligible with Norwegian in their spoken form because continental Scandinavian has diverged from them. While the two Germanic languages with the greatest numbers of speakers, English and German, have close similarities with Norwegian, neither is mutually intelligible with it. Norwegian is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Age.

Today there are two official forms of written Norwegian, Bokmål (Riksmål) and Nynorsk (Landsmål), each with its own variants. Bokmål developed from the Dano-Norwegian language that replaced Middle Norwegian as the elite language after the union of Denmark–Norway in the 16th and 17th centuries and then evolved in Norway, while Nynorsk was developed based upon a collective of spoken Norwegian dialects. Norwegian is one of the two official languages in Norway, along with Sámi, a group of Finno-Ugric languages spoken by less than one percent of the population. Norwegian is one of the working languages of the Nordic Council. Under the Nordic Language Convention, citizens of the Nordic countries who speak Norwegian have the opportunity to use it when interacting with official bodies in other Nordic countries without being liable for any interpretation or translation costs.

The Lombard language (Lombard: lombard, lumbard, lumbart or lombart, depending on the orthography; pronunciation: [lũˈbaːrt, lomˈbart]) belongs to the Gallo-Italic group within the Romance languages. It is characterized by a Celtic linguistic substratum and a Lombardic linguistic superstratum and is a cluster of homogeneous dialects that are spoken by millions of speakers in Northern Italy and southern Switzerland. These include most of Lombardy and some areas of the neighbouring regions, notably the far eastern side of Piedmont and the extreme western side of Trentino, and in Switzerland in the cantons of Ticino and Graubünden. The language is also spoken in Santa Catarina in Brazil by Lombard immigrants from the Province of Bergamo, in Italy.

Malay (UK: /məˈleɪ/ mə-LAY, US: /ˈmeɪleɪ/ MAY-lay; endonym: Bahasa Melayu, Jawi script: بهاس ملايو) is an Austronesian language spoken primarily by Malays in several islands of Maritime Southeast Asia and the Malay Peninsula on mainland Asia. The language is an official language of Brunei, Malaysia, and Singapore. Indonesian, a standardized variety of Malay, is the official language of Indonesia and one of the working languages of Timor-Leste. Malay is also spoken as a regional language of ethnic Malays in Indonesia, southeast Philippines and the southern part of Thailand. Altogether, it is spoken by 60 million people across Maritime Southeast Asia.

The language is pluricentric and a macrolanguage, i.e., a group of mutually intelligible speech varieties, or dialect continuum, that have no traditional name in common, and which may be considered distinct languages by their speakers. Several varieties of it are standardized as the national language (bahasa kebangsaan or bahasa nasional) of several nation states with various official names: in Malaysia, it is designated as either Bahasa Melayu ("Malay language") or in some instances, Bahasa Malaysia ("Malaysian language"); in Singapore and Brunei, it is called Bahasa Melayu ("Malay language") where it in the latter country refers to a formal standard variety set apart from its own vernacular dialect; in Indonesia, an autonomous normative variety called Bahasa Indonesia ("Indonesian language") is designated the bahasa persatuan/pemersatu ("unifying language" or lingua franca) whereas the term "Malay" (bahasa Melayu) refers to vernacular varieties of Malay indigenous to areas of Central to Southern Sumatra and West Kalimantan as the ethnic languages of Malay in Indonesia.

Modern Standard Arabic (MSA) or Modern Written Arabic (MWA) is the variety of standardized, literary Arabic that developed in the Arab world in the late 19th and early 20th centuries, and in some usages also the variety of spoken Arabic that approximates this written standard. MSA is the language used in literature, academia, print and mass media, and law and legislation, though it is generally not spoken as a first language, similar to Contemporary Latin. It is a pluricentric standard language taught throughout the Arab world in formal education, differing significantly from many vernacular varieties of Arabic that are commonly spoken as mother tongues in the area; these are only partially mutually intelligible with both MSA and with each other depending on their proximity in the Arabic dialect continuum.

Many linguists consider MSA to be distinct from Classical Arabic (CA; اللغة العربية الفصحى التراثية al-Lughah al-ʻArabīyah al-Fuṣḥā at-Turāthīyah) – the written language prior to the mid-19th century – although there is no agreed moment at which CA turned into MSA. There are also no agreed set of linguistic criteria which distinguish CA from MSA; however, MSA differs most markedly in that it either synthesizes words from Arabic roots (such as سيارة car (Sayyārah) or باخرة steamship (Bākhirah)) or adapts words from foreign languages (such as ورشة workshop (Warshah) or إنترنت Internet (Inṭirnēt)) to describe industrial and post-industrial life.

Egyptian Arabic, locally known as Colloquial Egyptian, or simply as Masri, is the most widely spoken vernacular Arabic variety in Egypt. It is part of the Afro-Asiatic language family, and originated in the Nile Delta in Lower Egypt. The estimated 111 million Egyptians speak a continuum of dialects, among which Cairene is the most prominent. It is also understood across most of the Arabic-speaking countries due to broad Egyptian influence in the region, including through Egyptian cinema and Egyptian music. These factors help make it the most widely spoken and by far the most widely studied variety of Arabic.

While it is primarily a spoken language, the written form is used in novels, plays and poems (vernacular literature), as well as in comics, advertising, some newspapers and transcriptions of popular songs. In most other written media and in radio and television news reporting, literary Arabic is used. Literary Arabic is a standardized language based on the language of the Qur'an, i.e. Classical Arabic. The Egyptian vernacular is almost universally written in the Arabic alphabet for local consumption, although it is commonly transcribed into Latin letters or in the International Phonetic Alphabet in linguistics text and textbooks aimed at teaching non-native learners. Egyptian Arabic's phonetics, grammatical structure, and vocabulary are influenced by the Coptic language; its rich vocabulary is also influenced by Turkish and by European languages such as French, Italian, Greek, and English.

In sociolinguistics, a variety, also known as a lect or an isolect, 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 language forms thought of as less prestigious or "proper" than the standard. Linguists speak of both standard and non-standard (vernacular) varieties as equally complex, valid, and full-fledged forms of language. Lect avoids the problem in ambiguous cases of deciding whether two varieties are distinct languages or dialects of a single language.

Variation at the level of the lexicon, such as slang and argot, is often considered in relation to particular styles or levels of formality (also called registers), but such uses are sometimes discussed as varieties as well.
