Proto-Indo-European language

From Wikipedia, the free encyclopedia

The Proto-Indo-European language (PIE) is the unattested, reconstructed common ancestor of the Indo-European languages, spoken by the Proto-Indo-Europeans. The existence of such a language has been accepted by linguists for over a century, and there have been many attempts at reconstruction. Nevertheless, many disagreements and uncertainties remain.

[edit] When and where was PIE spoken?

Main article: Proto-Indo-European Urheimat hypotheses

There are several competing hypotheses about when and where PIE was spoken. The Kurgan hypothesis is "the single most popular" model,^[1][2] postulating that the Kurgan culture of the Pontic steppe were the hypothesized speakers of the reconstructed Proto-Indo-European language. However, alternative theories such as the Anatolian urheimat have also gained acceptance.

The satemization process that caused the separation between Centum and Satem languages probably started as early as the fourth millennium BC^[3] and the only thing known for certain is that the proto language must have been differentiated into unconnected daughter dialects by the late 3rd millennium BC.

Mainstream linguistic estimates of the time between PIE and the earliest attested texts (ca. nineteenth century BC; see Kültepe texts) range around 1,500 to 2,500 years, with extreme proposals diverging up to another 100% on either side. Other than the aforementioned, predominant Kurgan hypothesis, proposed models include:

• the 4th millennium BC (excluding the Anatolian branch) in Armenia, according to the Armenian hypothesis (proposed in the context of Glottalic theory);
• the 5th millennium BC (4th excluding the Anatolian branch) in the Pontic-Caspian steppe, according to the popular Kurgan hypothesis;
• the 6th millennium BC or later in Northern Europe according to Lothar Kilian's and, especially, Marek Zvelebil's models of a broader homeland;
• the 6th millennium BC in India, according to Koenraad Elst's Out of India model;
• the 7th millennium BC in Anatolia (the 5th, in the Balkans, excluding the Anatolian branch), according to Colin Renfrew's Anatolian hypothesis;
• the 7th millennium BC (6th excluding the Anatolian branch), according to a 2003 glottochronological study^[4];
• before the 10th millennium BC, in the Paleolithic Continuity Theory.

[edit] History

Main article: Indo-European studies

The classical phase of Indo-European comparative linguistics leads from Franz Bopp's Comparative Grammar (1833) to August Schleicher's 1861 Compendium and up to Karl Brugmann's Grundriss published from the 1880s. Brugmann's junggrammatische re-evaluation of the field and Ferdinand de Saussure's development of the laryngeal theory may be considered the beginning of "contemporary" Indo-European studies.

PIE as described in the early 1900s is still generally accepted today; subsequent work is largely refinement and systematization, as well as the incorporation of new information, notably the Anatolian and Tocharian branches unknown in the 19th century.

Notably, the laryngeal theory, in its early forms discussed since the 1880s, became mainstream after Jerzy Kuryłowicz's 1927 discovery of the survival of at least some of these hypothetical phonemes in Anatolian. Julius Pokorny's Indogermanisches etymologisches Wörterbuch (1959) gave an overview of the lexical knowledge accumulated until the early 20th century, but neglected contemporary trends of morphology and phonology, and largely ignored Anatolian and Tocharian.

The generation of Indo-Europeanists active in the last third of the 20th century (such as Calvert Watkins, Jochem Schindler and Helmut Rix) developed a better understanding of morphology and, in the wake of Kuryłowicz's 1956 Apophonie, understanding of the ablaut. From the 1960s, knowledge of Anatolian became certain enough to establish its relationship to PIE; see also Indo-Hittite.

[edit] Method

Main articles: Historical linguistics and Indo-European sound laws

There is no direct evidence of PIE, because it was never written. All PIE sounds and words are reconstructed from later Indo-European languages using the comparative method and the method of internal reconstruction. An asterisk is used to mark reconstructed PIE words, such as *wódr̥ 'water', *ḱwṓn 'dog' (English hound), or *tréyes 'three (masculine)'. Many of the words in the modern Indo-European languages seem to have derived from such "protowords" via regular sound changes (e.g., Grimm's law).

As the Proto-Indo-European language broke up, its sound system diverged as well, according to various sound laws in the daughter languages. Notable among these are Grimm's law and Verner's law in Proto-Germanic, loss of prevocalic *p- in Proto-Celtic, reduction to h of prevocalic *s- in Proto-Greek, Brugmann's law and Bartholomae's law in Proto-Indo-Iranian, Grassmann's law independently in both Proto-Greek and Proto-Indo-Iranian, and Winter's law and Hirt's law in Balto-Slavic.

[edit] Relationship to other language families

Many higher-level relationships between PIE and other language families have been proposed, but these speculative connections are highly controversial. Perhaps the most widely accepted proposal is of an Indo-Uralic family, encompassing PIE and Uralic. The evidence usually cited in favor of this is the proximity of the proposed Urheimaten of the two families, the typological similarity between the two languages, and a number of apparent shared morphemes. Frederik Kortlandt, while advocating a connection, concedes that "the gap between Uralic and Indo-European is huge", while Lyle Campbell, an authority on Uralic, denies any relationship exists.

The existence of certain PIE typological features in Northwest Caucasian languages may hint at an early Sprachbund^[5] or substratum that reached geographically to the PIE homelands.^[6] This same type of languages, featuring complex verbs and of which the current Northwest Caucasian languages might have been the sole survivors, was cited by Peter Schrijver to indicate a local lexical and typological reminiscence in western Europe pointing to a possible Neolithic substratum.^[7]

Other proposals, further back in time (and correspondingly less accepted), link PIE and Uralic with Altaic and certain other families in Asia, such as Korean, Japanese, Chukotko-Kamchatkan and Eskimo-Aleut (representative proposals are Nostratic and Joseph Greenberg's Eurasiatic); or link some or all of these to Afro-Asiatic, Dravidian, etc., and ultimately to a single Proto-World family (nowadays mostly associated with Merritt Ruhlen). Various proposals, with varying levels of skepticism, also exist that join some subset of the putative Eurasiatic language families and/or some of the Caucasian language families, such as Uralo-Siberian, Ural-Altaic, Proto-Pontic, and so on.

[edit] Phonology

Main article: Proto-Indo-European phonology

[edit] Consonants

Alternative notations: The aspirated plosives are sometimes written as *bh, *dh, *ǵh, *gh, *gʷh; for the palatals, *k̑, *g̑ are often used; and *i̯, *u̯ can replace *y, *w.

The pronunciation of the laryngeals is disputed, at least *h₁ might not have been a fricative.

[edit] Vowels

• Short vowels: *e, *o (and possibly *a).
• Long vowels: *ē, *ō (and possibly *ā). Sometimes a colon (:) is employed instead of the macron sign to indicate vowel length (*a:, *e:, *o:).
• Diphthongs: *ei, *eu, *ēi, *ēu, *oi, *ou, *ōi, *ōu, (*ai, *au, *āi, *āu). Diphthongs are sometimes understood as combinations of a vowel plus a semivowel, e. g. *ey or *ei̯ instead of *ei.^[8]
• Vocalic allophones of laryngeals, nasals, liquids and semivowels: *h̥₁, *h̥₂, *h̥₃, *m̥, *n̥, *l̥, *r̥, *i, *u.
• Long variants of these vocalic allophones may have appeared already in the proto-language by compensatory lengthening (for example of a vowel plus a laryngeal): *m̥̄, *n̥̄, *l̥̄, *r̥̄, *ī, *ū.

It is often suggested that all *a and *ā were earlier derived from an *e preceded or followed by *h₂, but Mayrhofer^[9] has argued that PIE did in fact have *a and *ā phonemes independent of h₂.

[edit] Morphology

[edit] Root

Main article: Proto-Indo-European root

PIE was an inflected language, in which the grammatical relationships between words were signaled through inflectional morphemes (usually endings). The roots of PIE are basic morphemes carrying a lexical meaning. By addition of suffixes, they form stems, and by addition of desinences (usually endings), these form grammatically inflected words (nouns or verbs). PIE roots are understood to be predominantly monosyllabic with a basic shape CvC(C). This basic root shape is often altered by ablaut. Roots which appear to be vowel initial are believed by many scholars to have originally begun with a set of consonants, later lost in all but the Anatolian branch, called laryngeals (usually indicated *H, and often specified with a subscript number *h₁, *h₂, *h₃). Thus a verb form such as the one reflected in Latin agunt, Greek ἄγουσι (ágousi), Sanskrit ajanti would be reconstructed as *h₂eǵ-onti, with the element *h₂eǵ- constituting the root per se.

[edit] Ablaut

Main article: Indo-European ablaut

One of the distinctive aspects of PIE was its ablaut sequence that contrasted the vowel phonemes *o / *e / Ø [no vowel] within the same root. Ablaut is a form of vowel variation which changed between these three forms perhaps depending on the adjacent sounds and placement of stress in the word. These changes are echoed in modern Indo-European languages where they have come to reflect grammatical categories. These ablaut grades are usually referred to as: e-grade and o-grade, sometimes collectively termed full grade; zero-grade (no vowel, Ø); and lengthened grade (*ē or *ō). Modern English sing, sang, sung is an example of such an ablaut set and reflects a pre-Proto-Germanic sequence *sengw-, *songw-, *sngw-. Some scholars believe that the inflectional affixes of Indo European reflect ablaut variants, usually zero-grade, of older PIE roots. Often the zero-grade appears where the word's accent has shifted from the root to one of the affixes. Thus the alternation found in Latin est, sunt reflects PIE *h₁és-ti, *h₁s-ónti.

[edit] Noun

Main article: Proto-Indo-European noun

Proto-Indo-European nouns were declined for eight or nine cases (nominative, accusative, genitive, dative, instrumental, ablative, locative, vocative, and possibly a directive or allative)^[10]. There were three genders: masculine, feminine, and neuter.

There are two major types of declension, thematic and athematic. Thematic nominal stems are formed with a suffix *-o- (in vocative *-e) and the stem does not undergo ablaut. The athematic stems are more archaic, and they are classified further by their ablaut behaviour (acro-dynamic, protero-dynamic, hystero-dynamic and holo-dynamic, after the positioning of the early PIE accent (dynamis) in the paradigm).

[edit] Pronoun

Main article: Proto-Indo-European pronoun

PIE pronouns are difficult to reconstruct owing to their variety in later languages. This is especially the case for demonstrative pronouns. PIE had personal pronouns in the first and second person, but not the third person, where demonstratives were used instead. The personal pronouns had their own unique forms and endings, and some had two distinct stems; this is most obvious in the first person singular, where the two stems are still preserved in English I and me. According to Beekes^[11], there were also two varieties for the accusative, genitive and dative cases, a stressed and an enclitic form.

As for demonstratives, Beekes tentatively reconstructs a system with only two pronouns: *so / *seh₂ / *tod "this, that" and *h₁e / *(h₁)ih₂ / *(h₁)id "the (just named)" (anaphoric). He also postulates three adverbial particles *ḱi "here", *h₂en "there" and *h₂eu "away, again", from which demonstratives were constructed in various later languages.

[edit] Verb

Main article: Proto-Indo-European verb

The Indo-European verb system is complex and, as the noun, exhibits a system of ablaut. Verbs have at least four moods (indicative, imperative, subjunctive and optative, as well as possibly the injunctive, reconstructible from Vedic Sanskrit), two voices (active and mediopassive), as well as three persons (first, second and third) and three numbers (singular, dual and plural). Verbs are conjugated in at least three "tenses" (present, aorist, and perfect), which actually have primarily aspectual value. Indicative forms of the imperfect and (less likely) the pluperfect may have existed. Verbs were also marked by a highly developed system of participles, one for each combination of tense and mood, and an assorted array of verbal nouns and adjectival formations.

[edit] Numbers

Main article: Proto-Indo-European numerals

The Proto-Indo-European numerals are generally reconstructed as follows:

Lehmann^[14] believes that the numbers greater than ten were constructed separately in the dialects groups and that *ḱm̥tóm originally meant "a large number" rather than specifically "one hundred."

[edit] Particle

Main article: Proto-Indo-European particle

Many particles could be used both as adverbs and postpositions, like *upo "under, below". The postpositions became prepositions in most daughter languages. Other reconstructible particles include negators (*ne, *mē), conjunctions (*kʷe "and", *wē "or" and others) and an interjection (*wai!, an expression of woe or agony).

[edit] Sample texts

As PIE was spoken by a prehistoric society, no genuine sample texts are available, but since the 19th century modern scholars have made various attempts to compose example texts for purposes of illustration. These texts are educated guesses at best; Calvert Watkins in 1969 observes that in spite of its 150 years' history, comparative linguistics is not in the position to reconstruct a single well-formed sentence in PIE. Nevertheless, such texts do have the merit of giving an impression of what a coherent utterance in PIE might have sounded like.

Published PIE sample texts:

• Schleicher's fable (Avis akvasas ka) by August Schleicher (1868), modernized by Hermann Hirt (1939) and Winfred Lehmann and Ladislav Zgusta (1979)
• The king and the god (rēḱs deiwos-kʷe) by S. K. Sen, E. P. Hamp et al. (1994)
