Proto-Indo-European (English)

Where does "Proto-Indo-European" come from?

The term Proto-Indo-European is a modern construct formed by combining the prefix 'proto-', denoting an ancestor, with 'Indo-European,' a label coined in 1813 to describe the vast language family spanning from India to Europe. By linking these elements, linguists used the established geographical names derived from Ancient Greek roots to identify the hypothetical common ancestor of these global languages.
