Proto-Indo-European
To begin, Begin
-William Wordsworth
The Proto-Indo-European language (PIE) is the reconstructed common ancestor of the Indo-European languages, spoken by the Proto-Indo-Europeans. PIE was the first proposed proto-language to be widely accepted by linguists. Far more work has gone into reconstructing it than any other proto-language, and it is by far the most well-understood of all proto-languages at its time depth. During the 19th century, the vast majority of linguistic work was devoted to reconstruction of Proto-Indo-European or of daughter proto-languages such as Proto-Germanic, and most of the current techniques of historical linguistics were developed as a result.
