A dialect is a variety of language spoken by a particular group of people. This may include dominant and standardized varieties as well as vernacular, unwritten, or non-standardized varieties, such as those used in developing countries or isolated areas.
The non-standard dialects of a language with a writing system will operate at different degrees of distance from the standardized written form.
The Hmu language (hveb Hmub), also known as Qiandong Miao (黔东, Eastern Guizhou Miao), Central Miao (中部苗语), East Hmongic (Ratliff 2010), or (somewhat ambiguously) Black Miao, is a dialect cluster of Hmongic languages of China. The best studied dialect is that of Yǎnghāo (养蒿) village, Taijiang County, Guizhou Province.
Qanu (咯努), a Hmu variety, had 11,450 speakers as of 2000, and is spoken just south of Kaili City, Guizhou. The Qanu are ethnoculturally distinct from the other Hmu.
Old French (franceis, françois, romanz; French: ancien français [ɑ̃sjɛ̃ fʁɑ̃sɛ]) was the language spoken in most of the northern half of France approximately between the late 8th and mid-14th centuries. Rather than a unified language, Old French was a group of Romance dialects, mutually intelligible yet diverse. These dialects came to be collectively known as the langues d'oïl, contrasting with the langues d'oc, the emerging Occitano-Romance languages of Occitania, now Southern France.
The mid-14th century witnessed the emergence of Middle French, the language of the French Renaissance in the Île-de-France region; this dialect was a predecessor to Modern French. Other dialects of Old French evolved themselves into modern forms (Poitevin-Saintongeais, Gallo, Norman, Picard, Walloon, etc.), each with its linguistic features and history.
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.
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.
The Miyakoan language (宮古口/ミャークフツ Myākufutsu/Myākufutsї [mjaːkufutss̩] or 島口/スマフツ Sumafutsu/Sїmafutsї, Japanese: 宮古語, romanized: Miyako-go) is a diverse dialect cluster spoken in the Miyako Islands, located southwest of Okinawa. The combined population of the islands is about 52,000 (as of 2011). Miyakoan is a Southern Ryukyuan language, most closely related to Yaeyama. As of 2025, the number of competent native speakers is not definitively known. As a consequence of the Japanese government's Japanese language policy, which has traditionally referred to the language as 宮古方言 (Miyako hōgen), or simply a dialect of standard Japanese, it is not taught or used in schools. As a result, most people born after 1970 tend to not use the language except in songs and rituals, and the younger generation almost exclusively uses Japanese as their first language. UNESCO classified Miyakoan as a "definitely endangered" language in its Atlas of the World's Languages in Danger in February, 2009. The Endangered Languages Project currently classifies the language as "severely endangered."
Miyakoan is notable among the Japonic languages in that it allows non-nasal syllable-final consonants, something not found in most Japonic languages.
