Nostratic Languages - Constituent Language Families

Constituent Language Families

The language families proposed for inclusion in Nostratic vary, but all Nostraticists agree on a common core of language families, with differences of opinion appearing over the inclusion of additional families.

The three groups universally accepted among Nostraticists are Indo-European, Uralic, and Altaic; the validity of the Altaic family, while itself controversial, is taken for granted by Nostraticists. Nearly all also include the Dravidian and Kartvelian language families.

Following Pedersen, Illich-Svitych, and Dolgopolsky, most advocates of the theory have included Afroasiatic, though criticisms by Joseph Greenberg and others from the late 1980s onward suggested a reassessment of this position.

A fairly representative grouping, arranged in rough geographical order (and probable order of phylogenetic branching, following Starostin), would include:

• Afroasiatic
• Kartvelian
• Indo-European
• Uralic
• Dravidian
• Altaic
• Eskimo–Aleut

The Sumerian and Etruscan languages, usually regarded as language isolates, are thought by some to be Nostratic languages as well. Others, however, consider one or both to be members of another macrofamily called Dené–Caucasian.

Another notional isolate, the Elamite language, also figures in a number of Nostratic classifications. It is frequently grouped with Dravidian as Elamo-Dravidian.

In 1987 Joseph Greenberg proposed a similar macrofamily which he called Eurasiatic. It included the same "Euraltaic" core (Indo-European, Uralic, and Altaic), but excluded some of the above-listed families, most notably Afroasiatic. At about this time Russian Nostraticists, notably Sergei Starostin, constructed a revised version of Nostratic which was slightly broader than Greenberg's grouping but which similarly left out Afroasiatic.

Recently, a consensus has been emerging among proponents of the Nostratic hypothesis. Greenberg basically agreed with the Nostratic concept, though he stressed a deep internal division between its northern 'tier' (his Eurasiatic) and a southern 'tier' (principally Afroasiatic and Dravidian). The American Nostraticist Allan Bomhard considers Eurasiatic a branch of Nostratic alongside other branches: Afroasiatic, Elamo-Dravidian, and Kartvelian. Similarly, Georgiy Starostin (2002) arrives at a tripartite overall grouping: he considers Afroasiatic, Nostratic and Elamite to be roughly equidistant and more closely related to each other than to anything else. Sergei Starostin's school has now re-included Afroasiatic in a broadly defined Nostratic, while reserving the term Eurasiatic to designate the narrower subgrouping which comprises the rest of the macrofamily. Recent proposals thus differ mainly on the precise placement of Dravidian and Kartvelian.

According to Greenberg, Eurasiatic and Amerind form a genetic node, being more closely related to each other than either is to "the other families of the Old World". There are a number of hypotheses incorporating Nostratic into an even broader linguistic 'mega-phylum', sometimes called Borean, which would also include at least the Dené–Caucasian and perhaps the Amerind and Austric superfamilies. The term SCAN has been used for a group that would include Sino-Caucasian, Amerind, and Nostratic.
