Proto-Indo-European: how to reconstruct a language with no texts
No written record survives from the shared ancestor of Sanskrit, Latin, and English. Comparing languages can recover some features, but not its speakers’ exact words.
Reconstructing a language with no texts
Fortson's introduction to Indo-European language and culture explains the comparative method: regular sound correspondences across attested languages, from Sanskrit to Latin to Old English, are used to reconstruct a common ancestor. The research record models Proto-Indo-European at about 4500 to 2500 BCE and labels it a strong reconstruction whose internal chronology varies by model. Wiley-Blackwell ↗
What a reconstruction contains
Mallory and Adams' Oxford introduction shows the reconstructed vocabulary and what it suggests about the people who used it, from kinship terms to animals and technology. A reconstructed word is a hypothesis with a defined support set, not an attested form. Oxford University Press ↗
One branch, worked through
Ringe's From Proto-Indo-European to Proto-Germanic traces one dialect's path to a daughter proto-language in detail. The research record stores that descent as an established family relationship with high confidence, separate from any claim about where or who the speakers were. Oxford University Press ↗
Why genes cannot prove a language
The record's rules say that genetics, archaeological cultures, and ethnicity are never converted into a language edge without independent linguistic evidence. Why is that separation necessary, and what goes wrong when it is skipped?
