In 1786, while serving as a judge in Calcutta, India, Jones delivered a famous speech outlining his observations about the similarities between Sanskrit, Latin, and Greek. He declared that these languages, along with others, "had sprung from some common source which, perhaps, no longer exists."
While Jones was not the first to notice similarities between these languages, his speech was a pivotal moment in the development of the field of comparative linguistics. His work inspired generations of scholars to delve deeper into the connections between these languages, ultimately leading to the identification of the Indo-European family and its vast reach.
