Duala, which is known as Douala in French, is a Bantu language
spoken in Cameroon by about 87,700 people.
Duala first appeared in writing in 1862 in a translation of the
Bible. The orthography was reformed in 1932, and again in 1979 when
a common alphabet for the languages of Cameroon (Alphabet
Général des Langues Cameroun-aises) was created.
Duala has three tones: a high tone which is marked by
by an acute accent; a low tone which is unmarked, and a
falling-rising tone which marked by a caron (ˇ).
These accents are not always written.
