# Nostratic languages

Nostratic is a hypothetical language macrofamily including many of the language families of northern Eurasia first proposed in 1903. Though a historically important proposal, it is now generally considered a fringe theory. Its exact composition varies based on proponent; it typically includes the Kartvelian, Indo-European and Uralic languages; some languages from the similarly controversial Altaic family; the Afroasiatic languages; as well as the Dravidian languages (sometimes also Elamo-Dravidian).
The Nostratic hypothesis originates with Holger Pedersen in the early 20th century. The name "Nostratic" is due to Pedersen (1903), derived from the Latin nostrates "fellow countrymen". The hypothesis was significantly expanded in the 1960s by Soviet linguists, notably Vladislav Illich-Svitych and Aharon Dolgopolsky.
The hypothesis has fallen out of favour since the latter half of the 20th century and has limited degrees of acceptance, predominantly among a minority of Russian linguists. Linguists worldwide mostly reject Nostratic and many other macrofamily hypotheses with the exception of Dené–Yeniseian languages, which has been met with some degree of acceptance. In Russia, it is endorsed by a minority of linguists, such as Vladimir Dybo, but is not a generally accepted hypothesis. Some linguists take an agnostic view. Eurasiatic, a similar grouping, was proposed by Joseph Greenberg (2000) and endorsed by Merritt Ruhlen.

## History of research
### Origin of the Nostratic hypothesis

The last quarter of the 19th century saw various linguists putting forward proposals linking the Indo-European languages to other language families, such as Finno-Ugric and Altaic.
These proposals were taken much further in 1903 when Holger Pedersen proposed "Nostratic", a common ancestor for the Indo-European, Finno-Ugric, Samoyed, Turkish, Mongolian, Manchu, Yukaghir, Eskimo, Semitic, and Hamitic languages, with the door left open to the eventual inclusion of others.
The name Nostratic derives from the Latin word nostrās, meaning 'our fellow-countryman' (plural: nostrates) and has been defined, since Pedersen, as consisting of those language families that are related to Indo-European. Merritt Ruhlen notes that this definition is not properly taxonomic but amorphous, since there are broader and narrower degrees of relatedness, and moreover, some linguists who broadly accept the concept (such as Greenberg and Ruhlen himself) have criticised the name as reflecting the ethnocentrism frequent among Europeans at the time. Martin Bernal has described the term as distasteful because it implies that speakers of other language families are excluded from academic discussion. However, some people like Pedersen's older contemporary Henry Sweet attributed some of the resistance by Indo-European specialists to hypotheses of wider genetic relationships as "prejudice against dethroning [Indo-European] from its proud isolation and affiliating it to the languages of yellow races". Proposed alternative names such as Mitian, formed from the characteristic Nostratic first- and second-person pronouns mi 'I' and ti 'you' (more accurately 'thee'), have not attained the same currency.
An early supporter was the French linguist Albert Cuny—better known for his role in the development of the laryngeal theory—who published his Recherches sur le vocalisme, le consonantisme et la formation des racines en « nostratique », ancêtre de l'indo-européen et du chamito-sémitique ('Researches on the Vocalism, Consonantism, and Formation of Roots in "Nostratic", Ancestor of Indo-European and Hamito-Semitic') in 1943. Although Cuny enjoyed a high reputation as a linguist, the work was coldly received.

### Moscow School of Comparative Linguistics

While Pedersen's Nostratic hypothesis did not make much headway in the West, it became quite popular in the Soviet Union. Working independently at first, Vladislav Illich-Svitych and Aharon Dolgopolsky elaborated the first version of the contemporary form of the hypothesis during the 1960s. They expanded it to include additional language families. Illich-Svitych also prepared the first dictionary of the hypothetical language. Dolgopolsky's most recent Nostratic Dictionary was published in 2008, and is considered the most up-to-date attempt at a Nostratic lexicon.
A principal source for the items in Illich-Svitych's dictionary was the earlier work of Alfredo Trombetti (1866–1929), an Italian linguist who had developed a classification scheme for all the world's languages, widely reviled at the time and subsequently ignored by almost all linguists. In Trombetti's time, a widely held view on classifying languages was that similarity in inflections is the surest proof of genetic relationship. In the interim, the view had taken hold that the comparative method—previously used as a means of studying languages already known to be related and without any thought of classification—is the most effective means to establish genetic relationship, eventually hardening into the conviction that it is the only legitimate means to do so. This view was basic to the outlook of the new Nostraticists. Although Illich-Svitych adopted many of Trombetti's etymologies, he sought to validate them by a systematic comparison of the sound systems of the languages concerned.

## 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. While the validity of Altaic itself generally rejected by linguists, is taken for granted by Nostraticists. Nearly all also include the Kartvelian and Dravidian 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.
The Sumerian and Etruscan languages, regarded as language isolates by linguists, 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.
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.
Beginning in the early 2000s, a consensus emerged 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). 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 Kartvelian and Dravidian.
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. None of these proposed links have found wider acceptance outside of Nostraticists.
The following table summarizes the constituent language families of Nostratic, as described by Holger Pedersen, Vladislav Illich-Svitych, Sergei Starostin, and Aharon Dolgopolsky.

## Proposed features of Proto-Nostratic

According to Dolgopolsky, the Proto-Nostratic language had analytic structure, which he argues by diverging of post- and prepositions of auxiliary words in descendant languages. Dolgopolsky states three lexical categories to be in the Proto-Nostratic language:
* Lexical words
* Pronouns
* Auxiliary words
Word order was subject–object–verb when the subject was a noun, and object–verb–subject when it was a pronoun. Attributive (expressed by a lexical word) preceded its head. Pronominal attributive ('my', 'this') might follow the noun. Auxiliary words are considered to be postpositions.

## Status within comparative linguistics

The Nostratic hypothesis is not endorsed by the mainstream of comparative linguistics.
Nostraticists tend to refuse to include in their schema language families for which no proto-language has yet been reconstructed. This approach was criticized by Joseph Greenberg on the ground that genetic classification is necessarily prior to linguistic reconstruction, but this criticism has so far had no effect on Nostraticist theory and practice.
Certain critiques have pointed out that the data from individual, established language families that is cited in Nostratic comparisons often involves a high degree of errors; Campbell (1998) demonstrates this for Uralic data. Defenders of the Nostratic theory argue that were this to be true, it would remain that in classifying languages genetically, positives count for vastly more than negatives (Ruhlen 1994). The reason for this is that, above a certain threshold, resemblances in sound/meaning correspondences are highly improbable mathematically.
Pedersen's original Nostratic proposal synthesized earlier macrofamilies, some of which, including Indo-Uralic, involved extensive comparison of inflections. It is true the Russian Nostraticists initially emphasized lexical comparisons. Critics argue that were one to collect all the words from the various known Indo-European languages and dialects which have at least one of any four meanings, one could easily form a list that would cover any conceivable combination of two consonants and a vowel (of which there are only about 20×20×5 = 2000). Nostraticists respond that they do not compare isolated lexical items but reconstructed proto-languages. To include a word for a proto-language it must be found in a number of languages and the forms must be relatable by regular sound changes. In addition, many languages have restrictions on root structure, reducing the number of possible root-forms far below its mathematical maximum. These languages include, among others, Indo-European, Uralic, and Altaic—all the core languages of the Nostratic hypothesis. For a highly critical assessment of the work of the Moscow School, especially the work of Illich-Svitych, cf. Campbell and Poser 2008:243-264. Campbell and Poser argue that Nostratic, as reconstructed by Illich-Svitych and others, is "typologically flawed". For instance, they point out that, surprisingly, very few Nostratic roots contain two voiceless stops, which are less marked and should therefore occur more frequently, and where such roots do occur, in almost all cases the second stop occurs after a sonorant. In summary, Campbell and Poser reject the Nostratic hypothesis and, as a parting shot, state that they "seriously doubt that further research will result in any significant support for this hypothesized macro-family."
Proto-Indo-European *b[h]ars- seems to be a cultural loanword from Semitic (though several reputable Indo-Europeanists dispute this and consider it to be a native IE word). Much of the IE agricultural lexicon is not shared among all branches and seems to have been borrowed, thus supporting the view that the expansion of IE languages was post-Neolithic rather than a Neolithic one as postulated by Renfrew's theory.
