Sicilian ("sicilianu" ; in Italian: "Siciliano"; also known as Siculo ("siculu" ) or Calabro-Sicilian) is a Romance language spoken on the island of Sicily and its satellite islands.
 It is also spoken in southern and central Calabria (where it is called Southern Calabro), in the southern parts of Apulia, Salento (where it is known as Salentino), and Campania, on the Italian peninsula, where it is called Cilentano (Gordon, 2005).
 The "Ethnologue" (see below for more detail) describes Sicilian as being "distinct enough from Standard Italian to be considered a separate language" (Gordon) and is recognized as a "minority language" by UNESCO.
 Some assert that Sicilian represents the oldest Romance language derived from Vulgar Latin, but this is not a widely held view amongst linguists and is sometimes strongly criticized.
 Sicilian has the oldest literary tradition of the Italic languages.
Many words in the English lexicon are made up of Latinate words; that is, words which have entered the English language from a Romance language (usually Anglo-Norman), or were borrowed directly from Latin.
 Quite a few of these words can further trace their origins back to a Germanic source (usually Frankish), making them cognate with many native English words from Old English, yielding etymological twins.
 Many of these are Franco-German words, or French words of Germanic origin.
The language boundary in Brittany is the language border between the part of Brittany where Breton (a Celtic language) is spoken and the area in Brittany where Gallo (a Romance language) is spoken.
 The existence of this linguistic border led to differentiate the Celtic-speaking Lower Brittany (West) from the Romance-speaking Upper Brittany (East).
Moselle Romance is an extinct Romance language that developed after the fall of the Roman Empire along the Moselle river in modern-day Germany, near the border with France.
 Despite heavy Germanic influence, it persisted in isolated pockets until the 11th century.
Asturian ( ; autonym: "asturianu" ] ,<ref name="bable/asturiano">Art. 1 de la Ley 1/1998, de 23 de marzo, de uso y promoción del bable/asturiano/Law 1/93, of March 23, on the Use and Promotion of the Asturian Language</ref> formerly also known as "bable" ] ) is a West Iberian Romance language spoken in Principality of Asturias, Spain.
 Asturian is part of a wider linguistic group, the Astur-Leonese languages.
 The number of speakers is estimated at 100,000 (native) and 450,000 (second language).
 There are three main variants in the Astur-Leonese language family: Western, Central, and Eastern.
 For historical and demographic reasons, the standard is based on Central Asturian.
 Asturian has a distinct grammar, dictionary, and orthography.
 Regulated by the Academy of the Asturian Language, although it is not an official language of Spain it is protected under the Statute of Autonomy and is an elective language in schools.
French ("le français" ] or "la langue française" ] ) is a Romance language of the Indo-European family.
 It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages.
 French has evolved from Gallo-Romance, the spoken Latin in Gaul, and more specifically in Northern Gaul.
 Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) has largely supplanted.
 French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders.
 Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole.
 A French-speaking person or nation may be referred to as "Francophone" in both English and French.
A language border or language boundary is the line separating two language areas.
 The term is generally meant to imply a lack of mutual intelligibility between the two languages.
 If two adjacent languages or dialects are mutually intelligible, no firm border will develop, because the two languages can continually exchange linguistic inventions; this is known as a dialect continuum.
 A "language island" is a language area that is completely surrounded by a language border.
The Romance languages (sometimes called the Romanic languages, Latin languages, or Neo-Latin languages) are the modern languages that evolved from Vulgar Latin between the sixth and ninth centuries and that thus form a branch of the Italic languages within the Indo-European language family.
Dalmatian or Dalmatic was a Romance language spoken in the Dalmatia region of Croatia, and as far south as Kotor in Montenegro.
 The name refers to a tribe of the Illyrian linguistic group, Dalmatae.
 The Ragusan dialect of Dalmatian was the official language of the Republic of Ragusa, though in later times Venetian (representing the Romance language population), then Eastern Herzegovinian dialect of Serbo-Croatian (for the Slavophone population) came to supersede it.
The history of Belgium predates the founding of the modern state of that name in 1830.
 Belgium's history is intertwined with those of its neighbours: the Netherlands, Germany, France and Luxembourg.
 For most of its history, what is now Belgium was either a part of a larger territory, such as the Carolingian Empire, or divided into a number of smaller states, prominent among them being the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège and County of Luxembourg.
 Due to its strategic location and the many armies fighting on its soil, since the Thirty Years' War (1618–1648), Belgium has often been called the "battlefield of Europe" or the "cockpit of Europe".
 It is also remarkable as a European nation which contains, and is divided by, a language boundary between Latin-derived French and Germanic Dutch.
