原始印欧语数词

原始印欧语数词已经被现代语言学家基于跨越所有印欧语系语言所找到的相似性而重构了。本文列出并讨论它们的假定形式。

基数

基数重构如下:

数	重构(Sihler)[1]	重构(Beekes)[2]
1	*Hoi-no-/*Hoi-wo-/*Hoi-k(ʷ)o-; *sem-	*Hoi(H)nos
2	*d(u)wo-	*duoh₁
3	*trei- (完全等级) / *tri- (零等级)	*treies
4	*kʷetwor- (o-等级) / *kʷetur- (零等级) (参见kʷetwóres规则)	*kʷetuōr
5	*penkʷe	*penkʷe
6	*s(w)eḱs; 最初可能是 *weḱs	*(s)uéks
7	*septm̥	*séptm
8	*oḱtō, *oḱtou 或 *h₃eḱtō, *h₃eḱtou	*h₃eḱteh₃
9	*(h₁)newn̥	*(h₁)néun
10	*deḱm̥(t)	*déḱmt
20	*wīḱm̥t-; 最初可能是 *widḱomt-	*duidḱmti
30	*trīḱomt-; 最初可能是 *tridḱomt-	*trih₂dḱomth₂
40	*kʷetwr̥̄ḱomt-; 最初可能是 *kʷetwr̥dḱomt-	*kʷeturdḱomth₂
50	*penkʷēḱomt-; 最初可能是 *penkʷedḱomt-	*penkʷedḱomth₂
60	*s(w)eḱsḱomt-; 最初可能是 *weḱsdḱomt-	*ueksdḱomth₂
70	*septm̥̄ḱomt-; 最初可能是 *septm̥dḱomt-	*septmdḱomth₂
80	*oḱtō(u)ḱomt-; 最初可能是 *h₃eḱto(u)dḱomt-	*h₃eḱth₃dḱomth₂
90	*(h₁)newn̥̄ḱomt-; 最初可能是 *h₁newn̥dḱomt-	*h₁neundḱomth₂
100	*ḱm̥tom; 最初可能是 *dḱm̥tom	*dḱmtóm
1000	*ǵʰeslo-; *tusdḱomti (最初是“巨大的数”)	*ǵʰes-l-

其他重构典型的同 Beekes 和 Sihler 有轻微的差异(例如 Fortson^[3])。

元素 *-dḱomt- (在数20到90中)和 *dḱm̥t- (在100中)是在假定这些数为 *deḱm̥(t)“10”的派生词的假定上重构的。

Lehmann^[4] 相信大于10的数都是在方言群组中独立构造的而 *ḱm̥tóm 最初意味着“一个大数”而非特指100。

数的性

数3和4有带有后缀 *-s(o)r- 的阴性形式，分别重构为 *t(r)i-sr- 和 *kʷetwr̥-sr-。^[3]

数作为前缀

特殊形式的数被用作前缀，通常用来形成 bahuvrihi 复合(比如英语中的“five-fingered”):

数	前缀(Fortson)[5]
1- (together, same)	*sm̥-
2-	*dwi-
3-	*tri-
4-	*kʷ(e)tru- 或 *kʷetwr̥-

序数

序数是难于构造的，由于它们在后代语言中是各种各样的。下列重构是试探性的:^[6]

• “第1”在用 *pr̥h₃-(有关于某种副词含义“forth, forward, front”和小品词 *prō“forth”，因此最初意味着“foremost”或类似含义)加上各种后缀如 *-wo-, *-mo- 来形成。
• “第2”在后代语言使用了范围广泛的各种表达，经常无关于数2的词，所以不能重构出 PIE 形式。
• “第3”到“第6”被通过向基数加上后缀 *-t(ó)- 来形成: *tr̥-t(ó)- / *tri-t(ó)-“第三”等。
• “第7”到“第10”被通过向基数增加 thematic 元音 *-ó- 来形成: *oḱtow-ó-“第八”等。

结尾于音节主音鼻音的基数(7，9，10)在 thematic 元音前插入第二个鼻音，导致了后缀 *-mó- 和 *-nó-。这些后缀和后缀 *-t(ó)- 扩散到了临近的序数，例如吠陀梵语 aṣṭamá-“第八”和立陶宛语 deviñtas“第九”。
