Proto-Indo-European numerals
From HandWiki
Short description: Names of numbers in the Proto-Indo-European language
The numerals and derived numbers of the Proto-Indo-European language (PIE) have been reconstructed by modern linguists based on similarities found across all Indo-European languages. The following article lists and discusses their hypothesized forms.
Cardinal numbers
The cardinal numbers are reconstructed as follows:
| Number | Reconstruction (Sihler)[1] | Reconstruction (Beekes)[2] |
|---|---|---|
| one | *Hoi-no-/*Hoi-wo-/*Hoi-k(ʷ)o-; *sem- | *Hoi(H)nos ; sem-/sm̥- |
| two | *d(u)wo- | *du̯oh₁ |
| three | *trei- (full grade) / *tri- (zero grade) | *trei̯es |
| four | *kʷetwor- (o-grade) / *kʷetur- (zero grade) (see also the kʷetwóres rule) |
*kʷétu̯ōr |
| five | *penkʷe | *penkʷe |
| six | *s(w)eḱs; originally perhaps *weḱs | *(s)u̯éks |
| seven | *septm̥ | *séptm̥ |
| eight | *oḱtō, *oḱtou or *h₃eḱtō, *h₃eḱtou | *h₃eḱteh₃ |
| nine | *(h₁)newn̥ | *(h₁)néun |
| ten | *deḱm̥(t) | *déḱm̥t |
| twenty | *wīḱm̥t-; originally perhaps *widḱomt- | *du̯idḱm̥ti |
| thirty | *trīḱomt-; originally perhaps *tridḱomt- | *trih₂dḱomth₂ |
| forty | *kʷetwr̥̄ḱomt-; originally perhaps *kʷetwr̥dḱomt- | *kʷeturdḱomth₂ |
| fifty | *penkʷēḱomt-; originally perhaps *penkʷedḱomt- | *penkʷedḱomth₂ |
| sixty | *s(w)eḱsḱomt-; originally perhaps *weḱsdḱomt- | *u̯eksdḱomth₂ |
| seventy | *septm̥̄ḱomt-; originally perhaps *septm̥dḱomt- | *septm̥dḱomth₂ |
| eighty | *oḱtō(u)ḱomt-; originally perhaps *h₃eḱto(u)dḱomt- | *h₃eḱth₃dḱomth₂ |
| ninety | *(h₁)newn̥̄ḱomt-; originally perhaps *h₁newn̥dḱomt- | *h₁neundḱomth₂ |
| hundred | *ḱm̥tom; originally perhaps *dḱm̥tom | *dḱm̥tóm |
| thousand | *ǵʰeslo-; *tusdḱomti (originally "big hundred" ) | *ǵʰesl- |
Other reconstructions typically differ only slightly from Beekes and Sihler. A nineteenth-century reconstruction (by Brugmann) for thousand is *tūsḱmtiə.[3][4] See also Fortson 2004.[5]
The elements *-dḱomt- (in the numerals "twenty" to "ninety") and *dḱm̥t- (in "hundred") are reconstructed on the assumption that these numerals are derivatives of *deḱm̥(t) "ten".
Lehmann[6] believes that the numbers greater than ten were constructed separately in the dialect groups and that *ḱm̥tóm originally meant "a large number" rather than specifically "one hundred."
Gender of numerals
The numbers three and four had feminine forms with the suffix *-s(o)r-, reconstructed as *t(r)i-sr- and *kʷetwr̥-sr-, respectively.[5]
Numerals as prefixes
Special forms of the numerals were used as prefixes, usually to form bahuvrihis (like five-fingered in English):
| Number | Prefix (Fortson)[7] |
|---|---|
| one- (together, same) | *sm̥- |
| two- | *dwi- |
| three- | *tri- |
| four- | *kʷ(e)tru- or *kʷetwr̥- |
Ordinal numbers
The ordinal numbers are difficult to reconstruct due to their significant variation in the daughter languages. The following reconstructions are tentative:[8]
- "first" is formed with *pr̥h₃- (related to some adverbs meaning "forth, forward, front" and to the particle *prō "forth", thus originally meaning "foremost" or similar) plus various suffixes like *-mo-, *-wo- (cf. Latin primus, Russian perv-).
- "second": The daughter languages use a wide range of expressions, often unrelated to the word for "two" (including Latin and English), so that no PIE form can be reconstructed. A number of languages use the form derived from *h₂enteros meaning "the other [of two]" (cf. OCS vĭtorŭ, Lithuanian añtras, Old Icelandic annarr)
- "third" to "sixth" were formed from the cardinals plus the suffix *-t(ó)-: *tr̥-t(ó)- / *tri-t(ó)- "third" etc.
- "seventh" to "tenth" were formed by adding the thematic vowel *-ó- to the cardinal: *oḱtow-ó- "eighth" etc.
The cardinals ending in a syllabic nasal (seven, nine, ten) inserted a second nasal before the thematic vowel, resulting in the suffixes *-mó- and *-nó-. These and the suffix *-t(ó)- spread to neighbouring ordinals, seen for example in Vedic aṣṭamá- "eighth" and Lithuanian deviñtas "ninth".
Reflexes
Reflexes, or descendants of the PIE reconstructed forms in its daughter languages, include the following.
