This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Linguistics. As a rule, “pro-Altaicists” claim that “Proto-Altaic” is as reconstructible by means of the classic comparative method as any uncontroversial linguistic family; in support of this view, they have produced several attempts to assemble large bodies of etymological evidence for the hypothesis, backed by systems of regular phonetic correspondences between compared languages. Supporters of “Proto-Altaic,” commonly known as “(pro-)Altaicists,” claim that only divergence from an original common ancestor can account for the observed regular phonetic correspondences and other structural similarities, whereas “anti-Altaicists,” without denying the existence of such similarities, insist that they do not belong to the “core” layers of the respective languages and are therefore better explained as results of lexical borrowing and other forms of areal linguistic contact. The debate over the nature of the relationship between the various units that constitute “Altaic,” sometimes referred to as “the Altaic controversy,” has been one of the most hotly debated topics in 20th-century historical linguistics and a major focal point of studies dealing with the prehistory of Central and East Eurasia. The bulk of “Altaic” has traditionally included such uncontroversial families as Turkic, Mongolic, and Manchu-Tungusic; additionally, Japanese (Japonic) and Korean are also frequently seen as potential members of the larger Altaic family (the entire five branches are sometimes referred to as “Macro-Altaic”). Recent years have seen major shifts in the study of children’s pragmatic development.
Findings from these three domains suggest that children actively use pragmatic reasoning to delimit potential referents for newly encountered words, can take into account the perspective of a communicative partner, and are sensitive to some aspects of implicated and metaphorical meaning. The Old Semitic writing system gave rise to the modern alphabets used in thousands of unrelated contemporary languages. Some Afroasiatic languages, such as Egyptian, Akkadian, Phoenician, Hebrew, Arabic, and Ge’ez, have a longtime written tradition, but for many languages no writing system has yet been proposed or adopted. The term tends to refer to language phenomena such as Sheng or Engsh in Kenya, Tsotsitaal in South Africa, Nouchi in Ivory Coast, Camfranglais in Cameroon, and many more, both named and unnamed. A growing phenomena in urban centers on the African continent in the latter half of the 20th century and start of the 21st century has been what have been described as Urban Youth Languages,’ although the ‘urban’ moniker is increasingly being dropped as these phenomena spread out from cities to rural areas.
