Guthrie classification of Bantu languages
The 250 or so "Narrow Bantu languages" are conventionally divided up into geographic zones first proposed by Malcolm Guthrie (1967–1971).[1] 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 Guthrie's time a Zone J (made of languages formerly classified in groups D and E) has been set up as another possible genealogical group bordering the Great Lakes.
