Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. All oral languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with phoneme. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific.
The Hutu, also known as the Abahutu, are a Bantu ethnic or social group which is native to the African Great Lakes region. They mainly live in Rwanda, Burundi and the eastern Democratic Republic of the Congo, where they form one of the principal ethnic groups alongside the Tutsi and the Great Lakes Twa.
Whistled languages are linguistic systems that use whistling to emulate speech and facilitate communication between individuals.
Kinyarwanda, Rwandan or Rwanda, officially known as Ikinyarwanda, is a Bantu language and the national language of Rwanda. It is a dialect of the Rwanda-Rundi language that is also spoken in Burundi and adjacent parts of the Democratic Republic of the Congo, Uganda and Tanzania. Kinyarwanda is universal among the native population of Rwanda and is mutually intelligible with Kirundi, the national language of neighbouring Burundi. Kinyabwishya and Kinyamulenge are mutually intelligible dialects spoken in the North Kivu and South Kivu provinces of neighbouring DR Congo.
Comorian is the name given to a group of four Bantu languages spoken in the Comoro Islands, an archipelago in the southwestern Indian Ocean between Mozambique and Madagascar. It is named as one of the official languages of the Union of the Comoros in the Comorian constitution. Shimaore, one of the languages, is spoken on the disputed island of Mayotte, a French department claimed by Comoros.
The Shan language is the native language of the Shan people and is mostly spoken in Shan State, Myanmar. It is also spoken in pockets in other parts of Myanmar, in Northern Thailand, in Yunnan, in Laos, in Cambodia, in Vietnam and decreasingly in Assam and Meghalaya. Shan is a member of the Tai–Kadai language family and is related to Thai. It has five tones, which do not correspond exactly to Thai tones, plus a sixth tone used for emphasis. The term Shan is also used for related Northwestern Tai languages, and it is called Tai Yai or Tai Long in other Tai languages. Standard Shan, which is also known as Tachileik Shan, is based on the dialect of the city of Tachileik.
Meeussen's rule is a special case of tone reduction. It was first described in Bantu languages, but occurs in analyses of other languages as well, such as Papuan languages. The tonal alternation it describes is the lowering, in some contexts, of the last tone of a pattern of two adjacent High tones (HH), resulting in the pattern HL. The phenomenon is named after its first observer, the Belgian Bantu specialist A. E. Meeussen (1912–1978). In phonological terms, the phenomenon can be seen as a special case of the Obligatory Contour Principle.
Lisu is a tonal Tibeto-Burman language spoken in Yunnan, Northern Burma (Myanmar) and Thailand and a small part of India. Along with Lipo, it is one of two languages of the Lisu people. Lisu has many dialects that originate from the country in which they live. Hua Lisu, Pai Lisu and Lu Shi Lisu dialects are spoken in China. Although they are mutually intelligible, some have many more loan words from other languages than others.
Central Kilimanjaro, or Central Chaga, is a Bantu language of Tanzania spoken by the Chaga people.
Tonga (Chitonga), also known as Zambezi, is a Bantu language primarily spoken by the Tonga people who live mainly in the Southern province, Lusaka province, Central Province and Western province of Zambia, and in northern Zimbabwe, with a few in northwest Mozambique. The language is also spoken by the Iwe, Toka and Leya people among others, as well as many bilingual Zambians and Zimbabweans. In Zambia Tonga is taught in schools as first language in the whole of Southern Province, Lusaka and Central Provinces.
The Banyarwanda are a Bantu ethnolinguistic supraethnicity. The Banyarwanda are also minorities in neighboring DR Congo, Uganda, and Tanzania.
Iau or Turu is a Lakes Plain language of West Papua, Indonesia, spoken by about 2,100 people, native speakers of this language are the Turu people (Iau). Most speakers are monolingual, and their number is growing. Other peoples in the western Lakes Plain area speak basic Iau. Iau is heavily tonal, with 11 tones on nouns and 19 simple and compound tones on verbs.
Standard Cantonese pronunciation is that of Guangzhou, also known as Canton, capital of Guangdong Province. Hong Kong Cantonese is related to Guangzhou dialect, and they diverge only slightly. Yue dialects in other parts of Guangdong and Guangxi provinces like Taishanese, may be considered divergent to a greater degree.
Rwanda-Rundi is a group of Bantu languages, specifically a dialect continuum, spoken in Central Africa. Two dialects, Kirundi and Kinyarwanda, have been standardized as the national languages of Burundi and Rwanda respectively. These neighbouring dialects are mutually intelligible, but other dialects which are more distant ones may not be. The other dialects are spoken in the Democratic Republic of the Congo, Uganda, and Tanzania; Ha, with one million speakers, is the most widely spoken.
Jita is a Bantu language of Tanzania, spoken on the southeastern shore of Lake Victoria/Nyanza and on the island of Ukerewe.
Naki, or Munkaf, is an Eastern Beboid language of Cameroon and Nigeria. There is no name for the language; it is known by the villages it is spoken in, including Naki and Mekaf (Munkaf) in Cameroon and Bukwen and Mashi in Nigeria, the latter listed as separate languages by Ethnologue, though they are not distinct.
Ruuli is the Bantu language spoken by the Baruuli and Banyala people of Uganda primarily in Nakasongola and Kayunga districts. It is closely to the Nyoro language
Aushi, known by native speakers as Ikyaushi, is a Bantu language primarily spoken in the Lwapula Province of Zambia and the (Haut-)Katanga Province of the Democratic Republic of Congo. Although many scholars argue that it is a dialect of the closely related Bemba, native speakers insist that it is a distinct language. Nonetheless, speakers of both linguistic varieties enjoy extensive mutual intelligibility, particularly in the Lwapula Province.
Proto-Bantu is the reconstructed common ancestor of the Bantu languages, a subgroup of the Southern Bantoid languages. It is thought to have originally been spoken in West/Central Africa in the area of what is now Cameroon. About 6,000 years ago, it split off from Proto-Southern Bantoid when the Bantu expansion began to the south and east. Two theories have been put forward about the way the languages expanded: one is that the Bantu-speaking people moved first to the Congo region and then a branch split off and moved to East Africa; the other is that the two groups split from the beginning, one moving to the Congo region, and the other to East Africa.
Achille Emile Meeussen, also spelled Achiel Emiel Meeussen, or simply A.E. Meeussen (1912–1978) was a distinguished Belgian specialist in Bantu languages, particularly those of the Belgian Congo, Rwanda and Burundi. Together with the British scholar Malcolm Guthrie (1903–1972) he is regarded as one of the two leading experts in Bantu languages in the second half of the 20th century.
