[Dimmendaal, Gerrit J. (2011). ''Historical Linguistics and the Comparative Study of African Languages'', pp. 337ff.] 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 (more likely) is that the two groups split from the beginning, one moving to the Congo region, and the other to East Africa.

s, there is no record of Proto-Bantu. Its words and pronunciation have been
reconstructed by linguists. From the common vocabulary which has been reconstructed on the basis of present-day Bantu languages, it appears that agriculture, fishing, and the use of boats were already known to the Bantu people before their expansion began, but iron-working was still unknown. This places the date of the start of the expansion somewhere between 3000 BC and 800 BC.
A minority view casts doubt on whether Proto-Bantu, as a unified language, actually existed in the time before the Bantu expansion, or whether Proto-Bantu was not a single language but a group of related dialects. One scholar,
Roger Blench, writes: "The argument from comparative linguistics which links the highly diverse languages of zone A to a genuine reconstruction is non-existent. Most claimed Proto-Bantu is either confined to particular subgroups, or is widely attested outside Bantu proper." According to this hypothesis, Bantu is actually a

The homeland of Proto-Bantu was most likely in the upland forest fringes around the
Sanaga and
Nyong rivers of Southern Cameroon. It was formerly thought that proto-Bantu originated somewhere in the border region between Nigeria and Cameroon. However, new research revealed that was more likely the original area of Proto-Southern Bantoid, before it spread southwards into Cameroon long before Proto-Bantu emerged.
Phonology
Proto-Bantu is generally reconstructed to have a relatively small inventory of 11 consonants and 7 vowels.

Consonant clusters did not occur except for the "pre-nasalised" consonants.
The so-called "pre-nasalised" consonants were sequences of a nasal and a following obstruent. They could occur anywhere a single consonant was permitted, including word-initially. Pre-nasalised voiceless consonants were rare, as most were voiced. The nasal's articulation adapted to the articulation of the following consonant so the nasal can be considered a single unspecified nasal phoneme (indicated as ''*N'') which had four possible allophones. Conventionally, the labial pre-nasal is written *m while the others are written *n.
* *mb, *mp; phonemically *Nb, *Np
* *nd, *nt; phonemically *Nd, *Nt
* *nj, *nc; phonemically *Nj, *Nc (actually pronounced as *ɲj, *ɲc)
* *ng, *nk; phonemically *Ng, *Nk (actually pronounced as *ŋg, *ŋk)
The earlier velar nasal phoneme , which was present in the Bantoid languages, had been lost in Proto-Bantu.[Derek Nurse, Gérard Philippson (eds) (2006) ''The Bantu Languages''.] It still occurred phonetically in pre-nasalised consonants but not as a phoneme.
Vowels
The representation of the vowels may differ in particular with respect to the two "middle" levels of closedness. Some prefer to denote the near-close set as *e and *o, with the more open set represented as *ɛ and *ɔ.
Syllables always ended in a vowel but could also begin with one. Vowels could also occasionally appear in a sequence but did not form diphthong

s; two adjacent vowels were separate syllables. If two of the same vowel occurred together, that created a long vowel, but that was rare.
Tones
Proto-Bantu distinguished two tones, low and high. Each syllable had either a low or a high tone. A high tone is conventionally indicated with an acute accent (´), and a low tone is either indicated with a grave accent (`) or not marked at all.
Morphology
Noun classes
Proto-Bantu, like its descendants, had an elaborate system of noun class
In linguistics, a noun class is a particular category of nouns. A noun may belong to a given class because of the characteristic features of its referent, such as gender, animacy, shape, but such designations are often clearly conventional. Some ...
es. Noun stems were prefixed with a noun prefix to specify their meaning. Other words that related or referred to that noun, such as adjectives and verbs, also received a prefix that matched the class of the noun (" agreement" or "concord").
Maho offers a broad characterization of five types of Bantu concordial systems.[Maho, J. F. (1999). ''A comparative study of Bantu noun classes''.] Languages descended from Proto-Bantu can be classified into each of the five types.
* Type A: Traditional, strictly formal
* Type B: Traditional with general animate concords
* Type C: Animacy-based SG/PL-marking
* Type D: SG/PL-marking only
* Type E: No concords at all
The following table gives a reconstruction of the system of nominal classes. Spellings have been normalised to use the ''ɪ'' and ''ʊ'' notations. Guthrie's original work uses ''y'' to describe the palatal semi-vowel, which has been normalised to use the ''j'' notation.[Guthrie, M. (1970). ''Collected Papers on Bantu Linguistics''.]
An alternative list of Proto-Bantu noun classes from Good (2020:151) is as follows:[Good, Jeff. 2020. ''Niger-congo, with a Special Focus on Benue-congo'' in
Vossen, Rainer and Gerrit J. Dimmendaal (eds.). ''The Oxford Handbook of African Languages'' pp. 138–160. Oxford: Oxford University Press.]
Wilhelm Bleek's reconstruction consisted of sixteen noun prefixes. Carl Meinhof adapted Bleek's prefixes, changing some phonological features and adding more prefixes, bringing the total number to 21. A. E. Meeussen reduced Meinhof's reconstructed prefixes to 19, but added an additional locative prefix numbered 23. Malcolm Guthrie later reconstructed the same 19 classes as Meeussen, but removed locative prefix numbered 23.[
Hendrikse and Poulos proposed a semantic continuum for Bantu noun classes. Numbers identifying noun classes in the table are referenced from the above table giving a reconstruction of nominal classes.][
This arrangement permits the classification of noun classes via nonlinguistic factors like perception and cognition. Hendrikse and Poulos have grouped singular and plural classes (such as classes 1 and 2) together, and created "hybrid positions" between the varying categories (such as the placement of class 14).][
]
Noun class pairings
Classes 2, 4, 6, 8, 10, and 13 are generally accepted as being the plural forms of noun classes in Proto-Bantu. Classes 14 onward do not have a plural form defined as concretely as classes 1–13 do.
Meeussen proposed pairings of 1/2, 3/4, 5/6, 7/8, 9/10, 11/10, 12/13, 14/6, 15/6, and "probably" 19/13.[
Guthrie proposed pairings of 1/2, 1a/2, 3/4, 3, 5/6, 5, 6, 7/8, 9/10, 9, 11/10, 12/13, 14, 14/6.][
Maho combines pairings by De Wolf, Meeussen, and Guthrie, offering alternative pairings such as 3/10, 3/13, 9/4, 11/4, 12/4, 14/4, 14/10, 15/4, 19/4, and 19/10.][
]
Vocabulary
During the last hundred years, beginning with Carl Meinhof and his students, great efforts have been made to examine the vocabulary of the approximately 550 present day Bantu languages and to try to reconstruct the proto-forms from which they presumably came. Among other recent works is that by Bastin, Coupez, and Mann, which assembled comparative examples of 92 different words from all the 16 language zones established by Guthrie.[Schadeberg, T. C. in Nurse, D. & Philippson, G. (eds) (2006) ''The Bantu Languages'', pp. 154ff.]
Although some words are found only in certain of the Guthrie zones, others are found in every zone. These include for example *''mbʊ́à'' 'dog', *''-lia'' 'eat', *''ma-béele'' 'breasts', *''i-kúpa'' 'bone', *''i-jína'' 'name', *''-genda'' 'walk', *''mʊ-kíla'' 'tail', *''njɪla'' 'path', and so on. (The asterisks show that these are reconstructed forms, indicating how the words are presumed to have been pronounced before the Bantu expansion began.)
Other vocabulary items tend to be found in either one or the other of the two main Bantu dialect groups, the Western group (mainly covering Guthrie zones A, B, C, H, K, L, R) or the Eastern group (covering zones D, E, F, G, M, N, P, and S). Words reconstructed for these two groups are known as "Proto-Bantu A" ("PB-A") and "Proto-Bantu B" ("PB-B") respectively, whereas those which extend over the whole Bantu area are known as "Proto-Bantu X" (or "PB-X").[Bostoen & Bastin (2016), p. 4 (see External links).]
Building on the work done by A. E. Meeussen in the 1960s, a publicly searchable database of all the Bantu vocabulary items which have been established or proposed so far is maintained by the Royal Museum for Central Africa
