ProtoIndoEuropeas

Proto-Indo-European, often abbreviated as PIE, is the reconstructed common ancestor of the Indo-European languages. This hypothetical language is believed to have been spoken by a people known as the Proto-Indo-Europeans, who are thought to have lived somewhere in Eurasia between the 4th and 5th millennia BCE. Linguists reconstruct Proto-Indo-European through a comparative method, analyzing similarities and patterns across its descendant languages, which include most European languages, Iranian languages, and Indo-Aryan languages.

Key features of Proto-Indo-European, as reconstructed, include a complex system of noun declension, verb conjugation, and a rich phonological inventory. It is believed to have had at least eight cases for nouns and pronouns, and a system of grammatical genders. The reconstruction of its vocabulary provides insights into the culture and environment of its speakers, with words for kinship terms, domesticated animals, basic tools, and natural phenomena.

The exact homeland and culture of the Proto-Indo-Europeans remain subjects of scholarly debate. Major theories include the Kurgan hypothesis, which places their origin in the Pontic-Caspian steppe, and the Anatolian hypothesis, which suggests an earlier origin in Anatolia. The spread of Proto-Indo-European and its subsequent diversification into various branches is a significant topic in historical linguistics and archaeology. The study of Proto-Indo-European continues to evolve with new evidence and analytical methods.
