William the Clerk of Normandy (French: "Guillaume le Clerc de Normandie" ) (fl.
 1210/1211–1227/1238) was a Norman cleric and Old French poet.
 He is not the same person as the Scoto-Norman poet William the Clerk, who wrote the "Roman de Fergus", sometimes wrongly attributed to the Norman.
Jean Guillaume Roquille (26 October 1804 – 1 February 1860) was a French tinsmith and poet who wrote in the Franco-Provençal language.
Guillaume de Machaut (] ; sometimes spelled Machault; c. 1300 – April 1377) was a medieval French poet and composer.
 He is regarded by many musicologists as the greatest and most important composer of the 14th century.
 One of the earliest composers on whom significant biographical information is available, Daniel Leech-Wilkinson called Machaut "the last great poet who was also a composer".
 Well into the 15th century, Machaut's poetry was greatly admired and imitated by other poets, including Geoffrey Chaucer.
Guillaume Dubois or Guillaume Crétin (c. 1460 – 30 November 1525) was a French poet.
The Oaths of Strasbourg (Latin: "Sacramenta Argentariae" ; French: "Les Serments de Strasbourg" ; German: "Die Straßburger Eide" ) were mutual pledges of allegiance between Louis the German (†876), ruler of East Francia, and his half-brother Charles the Bald (†877), ruler of West Francia made on 12 February 842.
 They are written in three different languages: Medieval Latin, Old Gallo-Romance and Old High German, all in Caroline minuscule.
 The Romance passages are generally considered to be the earliest texts in a language that is distinctly Gallo-Romance.
Franco-Provençal (Francoprovençal), Arpitan or Romand (in Switzerland) (Franco-Provençal: "francoprovençâl, arpetan, patouès "; French: "francoprovençal, arpitan, patois" ; Italian: "francoprovenzale, arpitano" ) is a Gallo-Romance language spoken in east-central France, western Switzerland, northwestern Italy, and in enclaves in the Province of Foggia in Apulia, Italy.
 Franco-Provençal has several distinct dialects and is separate from but closely related to neighboring Romance languages: the langues d'oïl, Occitan, the Gallo-Italic languages, and Romansh.
 The name "Franco-Provençal" was given to the language by Graziadio Isaia Ascoli in the 19th century because it shared features with "French" and "Provençal" without belonging to either.
 "Arpitan", a neologism, is becoming a popular name for the language and the people who speak it.
 This name was popularized due to the lands where the Arpitan language is spoken or used to be the prevalent idiom, Arpitania.
 The name for the region comes from the term "Arpes", meaning Alps in Arpitan.
François Colletet (1628-1680?)
 was a French poet, the son of the poet Guillaume Colletet.
 His poetry was considered inferior to that of his father and he was ridiculed by Nicolas Boileau.
Paul Fort (1 February 1872 – 20 April 1960) was a French poet associated with the Symbolist movement.
 At the age of 18, reacting against the Naturalistic theatre, Fort founded the Théâtre d'Art (1890–93).
 He also founded and edited the literary reviews "Livre d'Art" with Alfred Jarry and "Vers et Prose" (1905–14) with poet Guillaume Apollinaire, which published the work of Paul Valéry and other important Symbolist writers.
 Fort is notable for his enormous volume of poetry, having published more than thirty volumes of ballads and, according to Amy Lowell for creating the polyphonic prose form in his 'Ballades francaises' .
Monégasque (natively "Munegascu") is a dialect of Ligurian, a Gallo-Romance language spoken in Monaco.
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.
