Japhetic languages

Indo-European studies is a field of linguistics and an interdisciplinary field of study dealing with Indo-European languages, both current and extinct. Its goal is to amass information about the hypothetical proto-language from which all of these languages are descended, a language dubbed Proto-Indo-European (PIE), and its speakers, the Proto-Indo-Europeans, including their society and religion. The studies cover where the language originated and how it spread. This article also lists Indo-European scholars, centres, journals and book series.

The term Indo-European itself now current in English literature, was coined in 1813 by the British scholar Sir Thomas Young, although at that time, there was no consensus as to the naming of the recently discovered language family. However, he seems to have used it as a geographical term. Among the other names suggested were:

Rask's japetisk or "Japhetic languages", after the old notion of "Japhetites" and ultimately Japheth, son of the Biblical Noah, parallels the term Semitic, from Noah's son Shem, and Hamitic, from Noah's son Ham. Japhetic and Hamitic are both obsolete, apart from occasional dated use of term "Hamito-Semitic" for the Afro-Asiatic languages.

In English, Indo-German was used by J. C. Prichard in 1826 although he preferred Indo-European. In French, use of indo-européen was established by A. Pictet (1836). In German literature, Indoeuropäisch was used by Franz Bopp since 1835, while the term Indogermanisch had already been introduced by Julius von Klapproth in 1823, intending to include the northernmost and the southernmost of the family's branches, as it were as an abbreviation of the full listing of involved languages that had been common in earlier literature. Indo-Germanisch became established by the works of August Friedrich Pott, who understood it to include the easternmost and the westernmost branches, opening the doors to ensuing fruitless discussions whether it should not be Indo-Celtic, or even Tocharo-Celtic.
