Guthrie classification of Bantu languages
|Africa, from approximately the equator south|
The approximate locations of the sixteen Guthrie Bantu zones, including the addition of a zone J
The 250 or so "Narrow Bantu languages" are conventionally divided up into geographic zones first proposed by Malcolm Guthrie (1967–1971). These were assigned letters A–S and divided into decades (groups A10, A20, etc.); individual languages were assigned unit numbers (A11, A12, etc.), and dialects further subdivided (A11a, A11b, etc.). This coding system has become the standard for identifying Bantu languages; it was the only practical way to distinguish many ambiguously named languages before the introduction of ISO 639-3 coding, and it continues to be widely used. Only Guthrie's Zone S is (sometimes) considered to be a genealogical group; since then a Zone J has been set up as another possible genealogical group bordering the Great Lakes.
The list is first summarized, with links to articles on accepted groups of Bantu languages (bold decade headings). Following that is the complete 1948 list, as updated by Guthrie in 1971 and by Maho in 2009.
The list below reflects Guthrie as updated by Maho (2009). Not included in detail are the Northeast Bantu languages characterized by Dahl's Law, which is thought to be a genealogical group, cuts across the Guthrie system, and is covered at Northeast Bantu. Other groups with dedicated articles, such as Southern Bantu (Zone S) are also only summarized here, so that the initial listing is only a summary and an index for other articles.
Note that Ethnologue made multiple changes to Guthrie in an attempt to make the classification more historically accurate. However, the changes are inconsistent, and Ethnologue has not been followed here, though it is publicly available online. Thus a code may mean different things depending on whether Guthrie or SIL is being followed. (See link below for the SIL code assignments.) The updates in Maho (2009), on the other hand, are designed to be compatible with the original values of the codes.
Bantu has long been divided into Northwest Bantu (Forest Bantu) and Central Bantu (Savanna Bantu) branches based upon tone patterns, but there is little agreement as to which Guthrie zones (or which parts of zones) should be in either, the dichotomy is dubious, and they have not been followed here.
Accepted genealogical groups within the Guthrie zones are boldfaced.
S Cameroon, Equatorial Guinea, N Gabon
- A10 Lundu–Balong : Oroko (likely one of the Sawabantu languages); the other languages apart from A15 Manenguba (that is, Bonkeng, Nkongho, Bafaw-Balong) may be Sawabantu as well.
- A20–30 Sawabantu languages; Bube (in Mbam?)
- A40a (reduced) Basaa languages
- A50 Bafia languages
- A60+40b Mbam languages (Jarawan added after Guthrie)
- A70 Beti language
- A80–90 Makaa–Njem languages
Zone A is sometimes considered Forest Bantu.
Guthrie's A60 and part of his A40 have been removed to the Southern Bantoid Mbam languages. Sawabantu may include some of the A10 languages apart from Manenguba, whereas Bube may belong in Mbam.
Southern Bantoid Jarawan was assigned to Zone A by Gerhardt (1982) and Blench (ms 2006, 2011), specifically to A60, within Mbam.
According to several scholars, including Blench, there can be no coherent concept of Bantu as long as many of the Zone A and perhaps Zone B languages are included.
S Gabon, W Congo, W DR-Congo
- B20 Kele languages (?Seki)
- B10–30 Tsogo languages (?Myene)
- B40 (with some H10) Sira languages
- B50 Nzebi languages
- B60 Mbete languages
- B70 (with some B80) Teke languages
- B80 (reduced) Boma–Dzing languages (Tsong/Songo?)
Zone B is sometimes considered Forest Bantu.
NE DR-Congo, N Congo
- C10 (with some C30) Ngondi–Ngiri languages
- C20 Mboshi languages
- C30 (with Mongo, etc) Bangi–Ntomba languages (Lingala et al.)
- C37+41 Buja–Ngombe languages
- C42 Bwela
- C40a Bati–Angba languages (Bwa)
- C50–60 Soko languages
- C70 Tetela languages
- C80 Bushoong languages
Zone C is sometimes considered Forest Bantu, sometimes Savanna Bantu.
- D10 Mbole–Enya languages (?Lengola)
- D20a Lega–Binja languages
- D20–30 Komo–Bira languages, (with C40a) Boan
- D28 Holoholo (perhaps in NE Bantu)
- D30 (unclassified): Guru (Boguru), Ngbinda, Kare (Kari), Nyanga-li (Gbati-ri, Mayeka)
- D33 Nyali languages (Beeke? Ngbee?, +Bodo?)
- D43–55 Nyanga–Buyi languages
- D54 Bembe (with Lega?)
D10, D30, and some of D20 and D40 are sometimes considered Forest Bantu, the others Savanna Bantu.
Kenya, apart from Swahili
The languages of Zone E have been reassigned: E10–E40 to Great Lakes Bantu languages; E50 Kikuyu–Kamba (Central Kenya Bantu) and E60 Chaga–Taita to Northeast Bantu; E70 Nyika to Northeast Bantu, mostly in Sabaki.
W & C Tanzania.
Much of F20 and F30, including the major language Sukuma, have been reclassified as Northeast Bantu, with Bungu to Rukwa and Sumbwa as Great Lakes. Mbugwe–Rangi, however, form a valid node by themselves.
Isanzu is sometimes classified as F30, as a variety of Nilamba, and sometimes thought to be a remnant of the Bantu languages spoken in the area before F-zone languages arrived.
E Tanzania, Comoros
- G50 (with Mbunga) Kilombero
NW Angola, W Congo
H10 and H40 are sometimes considered Forest Bantu, the others Savanna Bantu.
Kongo–Yaka may form a family, perhaps with B40 Sira.
Uganda, Rwanda–Burundi, near lakes Kivu & Victoria
E Angola, W Zambia
K20 Lozi is now classified as Southern Bantu. Some K30 languages have been reclassified as Kavango, but Luyana is an independent lineage. K40 Subiya–Totela has been reclassified as Botatwe, apart from Mbukushu, which appears to be an independent lineage.
S DR-Congo, C Zambia
L20 Songe (apart perhaps from Lwalu), L30 Luba, L40 Kaonde, and L60 Nkoya have been grouped as Luban.
E Zambia, SE DR-Congo
- M10–30 (with Bungu) Rukwa languages
- M40–50 (with Senga) Sabi languages
- M60 (with K40 Subia) Botatwe languages
Sabi–Bobatwe may be related.
Malawi and surrounding areas, C Mozambique
- N20–40 Nyasa languages
NE Mozambique, SE Tanzania
SW Angola, N Namibia, N Botswana
R20 Ovambo, R30 Herero, and R10 apart from Umbundu have been grouped together as Southwest Bantu. Yeyi forms its own lineage.
South Africa, Botswana, Zimbabwe, S. Mozambique.

- Guthrie's 1948 classification, in detail, with each language numbered
- Maho 2009. Guthrie 1971, in detail, with subsequent additions, corrections, and corresponding ISO codes as of Ethnologue 15. Coding conventions are explained in Nurse & Philippson (2003). They are (with invented examples):
- A capital letter is added for an additional dialect of an existing language. That is, A15C would be a dialect of language A15 in addition to Guthrie's dialects A15a and A15b.
- A third digit is added for an additional language. If its closest relative can be identified, the digit is added to that code. That is, A151 would be a non-Guthrie language closest to Guthrie's A15.
- If a close relative has not been identified, the digit is added to the decade code. That is, A101 would be a language geographically in group A10, but not particularly close to any of Guthrie's A10 languages, or not known well enough to further classify.
- Pidgins and creoles are indicated by adding a capital letter to the decade code. That is, A10A would be a pidgin or creole based on a language in group A10.
