Niger–Congo is a hypothetical language family spoken over the majority of sub-Saharan Africa. It unites the Mande languages, the Atlantic-Congo languages, and possibly several smaller groups of languages that are difficult to classify. If valid, Niger-Congo would be the world's largest in terms of member languages, the third-largest in terms of speakers, and Africa's largest in terms of geographical area. It is generally considered to be the world's largest language family in terms of the number of distinct languages, just ahead of Austronesian, although this is complicated by the ambiguity about what constitutes a distinct language; the number of named Niger–Congo languages listed by Ethnologue is 1,540.
Benue–Congo is a major branch of the Volta-Congo languages which covers most of Sub-Saharan Africa.
Southern Bantoid is a branch of the Bantoid language family. It consists of the Bantu languages along with several small branches and isolates of eastern Nigeria and west-central Cameroon. Since the Bantu languages are spoken across most of Sub-Saharan Africa, Southern Bantoid comprises 643 languages as counted by Ethnologue, though many of these are mutually intelligible.
The approximately 450 Oceanic languages are a branch of the Austronesian languages. The area occupied by speakers of these languages includes Polynesia, as well as much of Melanesia and Micronesia. Though covering a vast area, Oceanic languages are spoken by only two million people. The largest individual Oceanic languages are Eastern Fijian with over 600,000 speakers, and Samoan with an estimated 400,000 speakers. The Gilbertese (Kiribati), Tongan, Tahitian, Māori and Tolai languages each have over 100,000 speakers. The common ancestor which is reconstructed for this group of languages is called Proto-Oceanic.
Tiv is a Tivoid language spoken in some states in North Central Nigeria, with some speakers in Cameroon. It had over 4.6 million speakers in 2020. The largest population of Tiv speakers are found in Benue state in Nigeria. The language is also widely spoken in the Nigerian states of Plateau, Taraba, Nasarawa, Cross River, Adamawa, Kaduna, and Abuja. It is by far the largest of the Tivoid languages, a group of languages belonging to the Southern Bantoid languages
Defaka is an endangered and divergent Nigerian language of uncertain classification. It is spoken in the Opobo–Nkoro LGA of Rivers State, in the Defaka or Afakani ward of Nkọrọ town and Ịwọma Nkọrọ. The low number of Defaka speakers, coupled with the fact that other languages dominate the region where Defaka is spoken, edges the language near extinction on a year-to-year basis. It is generally classified in an Ijoid branch of the Niger–Congo family. However, the Ijoid proposal is problematic. Blench (2012) notes that "Defaka has numerous external cognates and might be an isolate or independent branch of Niger–Congo which has come under Ịjọ influence."
There are over 525 native languages spoken in Nigeria. The official language and most widely spoken lingua franca is English, which was the language of Colonial Nigeria. Nigerian Pidgin – an English-based creole – is spoken by 30 million people in Nigeria.
The Beboid languages are any of several groups of languages spoken principally in southwest Cameroon, although two languages are spoken over the border in Nigeria. They are probably not most closely related to each other. The Eastern Beboid languages may be most closely related to the Tivoid and Momo groups, though some of the geographical Western Beboid grouping may be closer to Ekoid and Bantu.
Mantsi is an endangered Afro-Asiatic language spoken in Mangas town in Bauchi State, Nigeria. Blench (2020) reports that it is also called Mantsi. According to Blench, the structure of Mantsi differs significantly from the other South Bauchi languages.
The Grassfields languages are a branch of the Southern Bantoid languages spoken in the Western High Plateau of Cameroon and some parts of Taraba state, Nigeria. Better known Grassfields languages include the Eastern Grassfields languages, Bamun, Yamba, Bali, and Bafut and the Ring languages, Kom, Nso, and Oku. Almost all of these languages are closely related, sharing approximately half of their vocabulary.
Ebira is a Niger-Congo language. It is spoken by around 2 million people in North central Nigeria. It is the most divergent Nupoid language.
The twelve Mambiloid languages are languages spoken by the Mambila and related peoples mostly in eastern Nigeria and in Cameroon. In Nigeria the largest group is Mambila. In Cameroon the largest group is Vute.
The Southwest Grassfields, traditionally called Western Momo when considered part of the Momo group or when Momo is included in Grassfields, are a small branch of the Southern Bantoid languages spoken in the Western grassfields of Cameroon.
The Momo languages are a group of Grassfields languages spoken in the Western High Plateau of Cameroon.
Buru and Angwe constitute a potentially rather divergent Southern Bantoid language spoken in Sardauna LGA, Taraba State of Nigeria.
Daka is one of two languages spoken by the Chamba people in Nigeria, the other being Chamba Leko.
The Koma language is a language cluster belonging to the Duru branch of Savannas languages of Cameroon. Blench (2004) includes three varieties separated in Ethnologue, Koma Ndera, Gɨmne, and Gɨmnɨme; within Koma Ndera, speakers of the marginal dialects, Gomnome and Ndera, can scarcely understand one another, though both understand the central dialect, Gomme.
Ahwai, also called the Ndunic languages, is a Plateau language cluster spoken to the southwest of Fadan Karshi in Sanga LGA, Kaduna State, Nigeria. Most villages are located at the foot of the Ahwai Mountains in Kaduna State.
Bitare is a Tivoid language of Nigeria and Cameroon.
Iyive, also referred to as Uive, Yiive, Ndir, Asumbos, is a severely endangered Bantoid language spoken in Nigeria and Cameroon. The ethnic group defined by use of this language is the Ndir.
