| Definition -

1. The hypothetical ancestral language of the Nostratic family is called Proto-Nostratic.
Etymology - The Nostratic hypothesis was proposed by Holger Pedersen in the early 20th century. The name derives from the Latin nostrates, fellow countrymen. The hypothesis was significantly expanded in the 1960s by Soviet linguists, notably Vladislav Illich-Svitych and Aharon Dolgopolsky.
