I asked chat gpt what "Nostratic" means. Here's its response

Nostratic is a hypothetical language family that is proposed to include a group of ancient languages that are believed to be related to each other. This proposed family of languages is not universally accepted by linguists, and there is much debate about its validity.

The Nostratic hypothesis proposes that a number of language families, including Indo-European, Uralic, Altaic, Dravidian, Kartvelian, and Afro-Asiatic, among others, are all descended from a common ancestral language called Proto-Nostratic. This ancestral language is believed to have been spoken thousands of years ago, possibly in the region that is now the Caucasus Mountains.

Linguists who support the Nostratic hypothesis point to similarities between words and grammar structures in these language families as evidence of a common origin. However, this theory remains controversial, and many linguists are skeptical of the idea that such a distant language family can be reconstructed with any degree of certainty.
