WThe Bahnaric languages are a group of about thirty Austroasiatic languages spoken by about 700,000 people in Vietnam, Cambodia, and Laos. Paul Sidwell notes that Austroasiatic/Mon–Khmer languages are lexically more similar to Bahnaric and Katuic languages the closer they are geographically, independently of which branch of the family they belong to, but that Bahnaric and Katuic do not have any shared innovations that would suggest that together they form a branch of the Austroasiatic family, rather forming separate branches.
WCantonese is a language within the Chinese (Sinitic) branch of the Sino-Tibetan languages originating from the city of Guangzhou and its surrounding area in Southeastern China. It is the traditional prestige variety of the Yue Chinese dialect group, which has over 80 million native speakers. While the term Cantonese specifically refers to the prestige variety, it is often used to refer to the entire Yue subgroup of Chinese, including related but largely mutually unintelligible languages and dialects such as Taishanese.
WCham is a Malayo-Polynesian language of the Austronesian family, spoken by the Chams of Southeast Asia. It is spoken primarily in the territory of the former Kingdom of Champa, which spanned modern Eastern Cambodia and Southern Vietnam. The Western variety is spoken by 220,000 people in Cambodia and 25,000 people in Vietnam. As for the Eastern variety, there are about 73,000 speakers in Vietnam, for a total of approximately 320,000 speakers.
WFrench 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 evolved from Gallo-Romance, the Latin spoken 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) 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.
WHakka is a language group of varieties of Chinese, spoken natively by the Hakka people throughout Southern China and Taiwan and throughout the diaspora areas of East Asia, Southeast Asia and in overseas Chinese communities around the world.
WHmong / Mong is a dialect continuum of the West Hmongic branch of the Hmongic languages spoken by the Hmong People of Sichuan, Yunnan, Guizhou, Guangxi, Hainan, northern Vietnam, Thailand, and Laos. There are some 2.7 million speakers of varieties that are largely mutually intelligible, including over 280,000 Hmong Americans as of 2013. Over half of all Hmong speakers speak the various dialects in China, where the Dananshan (大南山) dialect forms the basis of the standard language. However, Hmong Daw (White) and Mong Njua (Green) are widely known only in Laos and the United States; Dananshan is more widely known in the native region of Hmong.
WThe fifteen Katuic languages form a branch of the Austroasiatic languages spoken by about 1.3 million people in Southeast Asia. People who speak Katuic languages are called the Katuic peoples. Paul Sidwell is the leading specialist on the Katuic languages. He notes that Austroasiatic/Mon–Khmer languages are lexically more similar to Katuic and Bahnaric the closer they are geographically. He says this geographic similarity is independent of which branch of the family each language belongs to. He also says Katuic and Bahnaric do not have any shared innovations, so they do not form a single branch of the Austroasiatic family, but form separate branches.
WKhmer is an Austroasiatic language spoken by the Khmer people, and the official and national language of Cambodia. With approximately 16 million speakers, it is the second most widely spoken Austroasiatic language. Khmer has been influenced considerably by Sanskrit and Pali, especially in the royal and religious registers, through Hinduism and Buddhism. It is also the earliest recorded and earliest written language of the Mon–Khmer family, predating Mon and Vietnamese, due to Old Khmer being the language of the historical empires of Chenla, Angkor and, presumably, their earlier predecessor state, Funan.
WThe Mienic or Yao languages are spoken by the Yao people of China, Vietnam, Laos, and Thailand.
WNguồn is a Vietic language spoken by the Nguồn people in the Trường Sơn mountains in Vietnam's North Central Coast region as well as in nearby regions of Laos.
WSouthwestern Mandarin, also known as Upper Yangtze Mandarin, is a Mandarin Chinese language spoken in much of Southwest China, including in Sichuan, Yunnan, Chongqing, Guizhou, most parts of Hubei, the northwestern part of Hunan, the northern part of Guangxi and some southern parts of Shaanxi and Gansu. Southwest Mandarin is about 50% mutually intelligible with Standard Chinese.
WTai Daeng, Táy-Môc-Châu or Red Tai is the language of the Tai Daeng people of northwestern Vietnam and across the border into northeastern Laos. It belongs to the Tai language family, being closely connected with Black Tai and White Tai, as well as being more distantly related to the language spoken in modern Thailand.
WVietnamese is an Austroasiatic language that originated in Vietnam, where it is the national and official language. It is by far the most spoken Austroasiatic language with over 90 million native speakers, at least seven times more than Khmer, the next most spoken Austroasiatic language. Its vocabulary has had significant influence from Chinese and French. It is the native language of the Vietnamese (Kinh) people, as well as a second language or first language for other ethnic groups in Vietnam. As a result of emigration, Vietnamese speakers are also found in other parts of Southeast Asia, East Asia, North America, Europe, and Australia. Vietnamese has also been officially recognized as a minority language in the Czech Republic.
