As elsewhere in the world, languages in Africa are endangered. The estimates for language loss on a world scale likely hold for Africa as well. Although the particular group of factors at work in Africa may be unique, they come from a well-established inventory familiar elsewhere. The forces reducing African language diversity come from the combination of a set of macro socioeconomic factors and historical events, such as colonization and globalization, coupled with local factors such as military conquest and misguided government policies. Simple demographic factors, such as number of speakers, are also important: the less widely spoken languages are more severely threatened than are those spoken more widely. The shift from African languages is to both European languages and the more widely spoken languages on the continent. Shifts also occur to localized or appropriated versions of the two. Climatic factors, most notably global warming, have played and will continue to play a role as well; the correlation between biological and linguistic diversity has often been remarked. For example, with the growth of plantation economies and the destruction of rain forests, there is a concomitant reduction in linguistic diversity.
Language Endangerment in Africa
Dalmatian is an extinct group of Romance varieties spoken on the eastern Adriatic seaboard, best known from its Vegliote variety, spoken on the island of Krk (also called Veglia). Vegliote is principally represented by the linguistic testimony of its last speaker, Tuone Udaina, who died at the end of the 19th century. By the time Udaina’s Vegliote could be explored by linguists (principally by Matteo Bartoli), it seems that he had no longer actively spoken the language for decades, and his linguistic testimony is imperfect, in that it is influenced for example by the Venetan dialect that he habitually spoke. Nonetheless, his Vegliote reveals various distinctive and recurrent linguistic traits, notably in the domain of phonology (for example, pervasive and complex patterns of vowel diphthongization) and morphology (notably a general collapse of the general Romance inflexional system of tense and mood morphology, but also an unusual type of synthetic future form).
