Low Franconian in the context of "Aschaffenburg (district)"

Essen (German pronunciation: [ˈɛsn̩] ) is the central and, after Dortmund, second-largest city of the Ruhr, the largest urban area in Germany. Its population of 574,082 makes it the fourth-largest city of North Rhine-Westphalia after Cologne, Düsseldorf and Dortmund, as well as the tenth-largest city of Germany. Essen lies in the larger Rhine-Ruhr metropolitan region, second largest by GDP in the EU, and is part of the cultural area of Rhineland. Due to its central location in the Ruhr, Essen is often regarded as the Ruhr's "secret capital".

Two rivers flow through the city: the Emscher in the north, and in the south the Ruhr River, which is dammed in Essen to form the Lake Baldeney [de] and Lake Kettwig [de] reservoirs. The central and northern boroughs of Essen historically belong to the Low German Westphalian dialects area, and the south of the city to the Low Franconian Bergish area.

German dialects are the various traditional local varieties of the German language. Though varied by region, those of the southern half of Germany beneath the Benrath line are dominated by the geographical spread of the High German consonant shift, and the dialect continuum that connects High German to the neighboring varieties of Low Franconian (Dutch) and Low German.

The varieties of German are conventionally grouped into Upper German, Central German and Low German; Upper and Central German form the High German subgroup. Standard German is a standardized form of High German, developed in the early modern period based on a combination of Central German and Upper German varieties.

French Flanders (French: Flandre française [flɑ̃dʁ(ə) fʁɑ̃sɛːz]; Dutch: Frans-Vlaanderen; West Flemish: Frans-Vloandern) is a historical and cultural region of France. it was historically part of the historical County of Flanders, now Flanders In Belgium where Flemish—a Low Franconian dialect cluster of Dutch—was (and to some extent, still is) traditionally spoken along with Roman Flemish, typically referred to as a French dialect (also called Ch’ti or, most commonly, Picard). The region lies in the modern-day northern French region of Hauts-de-France, and roughly corresponds to the arrondissements of Lille, Douai and Dunkirk on the northern border with Belgium. Together, with French Hainaut and Cambrésis, it makes up the French Department of Nord.

Krefeld (/ˈkreɪfɛld, -ɛlt/ KRAY-feld, -⁠felt, German: [ˈkʁeːfɛlt] ; Limburgish: Krieëvel [ˈkʀiə˦vəl]), also spelled Crefeld until 1925 (though the spelling was still being used in British papers throughout the Second World War), is a city in North Rhine-Westphalia, in western Germany. It is located northwest of Düsseldorf, its center lying just a few kilometers to the west of the river Rhine; the borough of Uerdingen is situated directly on the Rhine. Because of its economic past, Krefeld is often referred to as the "Velvet and Silk City". It is accessed by the autobahns A57 (Cologne–Nijmegen) and A44 (Aachen–Düsseldorf–Dortmund–Kassel).

Krefeld's residents now speak Hochdeutsch, or standard German, but the native dialect is a Low Franconian variety, sometimes locally called Krefelder Platt, Krieewelsch Platt, or sometimes simply Platt. The Uerdingen line isogloss, separating general dialectical areas in Germany and neighboring Germanic-speaking countries, runs through and is named after Krefeld's Uerdingen district, originally an independent municipality.

In historical linguistics, the High German consonant shift or second Germanic consonant shift is a phonological development (sound change) that took place in the southern parts of the West Germanic dialect continuum. The shift is used to distinguish High German from other continental West Germanic languages, namely Low Franconian (including standard Dutch) and Low German, which experienced no shift. The shift resulted in the affrication or spirantization of the West Germanic voiceless stop consonants /t/, /p/, and /k/, depending on position in a word. A related change, the devoicing of the voiced stopped consonants /d/, /b/ and /ɡ/, was less widespread, and only the devoicing of /d/ is found in most dialects.

There is no consensus on when the High German consonant shift occurred; it probably began between the 3rd and 5th centuries and was complete before the first written examples in Old High German, the earliest recorded stage of High German, were produced in the 8th century. There is also no consensus on where or how the shift proceeded.

An isogloss, also called a heterogloss, is the geographic boundary of a certain linguistic feature, such as the pronunciation of a vowel, the meaning of a word, or the use of some morphological or syntactic feature. Isoglosses are a subject of study in dialectology, in which they demarcate the differences between regional dialects of a language; in areal linguistics, in which they represent the extent of borrowing of features between languages in contact with one another; and in the wave model of historical linguistics, in which they indicate the similarities and differences between members of a language family.

Major dialects are typically demarcated by bundles of isoglosses, such as the Benrath line that distinguishes High German from the other West Germanic languages and the La Spezia–Rimini Line that divides the Northern Italian languages and Romance languages west of Italy from Central Italian dialects and Romance languages east of Italy. However, an individual isogloss may or may not have any coterminus with a language border. For example, the front-rounding of /y/ cuts across France and Germany, while the /y/ is absent from Italian and Spanish words that are cognates with the /y/-containing French words.

Zeelandic (Zeeuws: Zeêuws; Dutch: Zeeuws [zeːu̯s] ; West Flemish: Zêeuws) is a group of language varieties spoken in the southwestern parts of the Netherlands. It is currently considered a Low Franconian dialect of Dutch, but there have been movements to promote the status of Zeelandic from a dialect of Dutch to a separate regional language, which have been denied by the Dutch Ministry of Internal Affairs. More specifically, it is spoken in the southernmost part of South Holland (Goeree-Overflakkee) and large parts of the province of Zeeland, with the notable exception of eastern Zeelandic Flanders.

It has notable differences from Standard Dutch mainly in pronunciation but also in grammar and vocabulary, which separates it clearly from Standard Dutch. This makes mutual intelligibility with speakers of Standard Dutch difficult.

Flemish (Vlaams [vlaːms] ) is a Low Franconian dialect cluster of the Dutch language. It is sometimes referred to as Flemish Dutch (Vlaams-Nederlands), Belgian Dutch (Belgisch-Nederlands [ˈbɛlɣis ˈneːdərlɑnts] ), or Southern Dutch (Zuid-Nederlands). Flemish is native to the region known as Flanders in northern Belgium; it is spoken by Flemings, the dominant ethnic group of the region. Outside of Belgium Flanders, it is also spoken to some extent in French Flanders and the Dutch Zeelandic Flanders.

Weser–Rhine Germanic languages (or Rhine–Weser Germanic, German: Rheinweser-germanisch), sometimes also referred to as Istvaeonic languages, are a proposed Frank-related subgroup of the West Germanic languages which would in terms of modern languages unite both West Central German dialects and Low Franconian dialects including standard Dutch.

According to original versions of this proposal, introduced by the German linguist Friedrich Maurer (1898-1984), this subgroup descends from a distinct Frankish language, while the related ancestral languages of the so called Elbe Germanic dialects to the south, and North Sea Germanic languages to the north, only subsequently became smoothly connected within the same dialect continuum. Maurer's proposals were influenced not only by linguistic evidence, but also by the Germanic archaeological provinces defined by Raphael von Uslar in 1938, which include the so called Rhine-Weser Germanic peoples, and by early Roman era reports of the Istvaeones – a group of Germanic peoples which lived near the River Rhine, and understood themselve to share a distinct common ancestry, according to their descriptions by Tacitus and Pliny the Elder.
