As a note, Sanskrit is a "sibling" or cousin of Latin or Greek in the family tree of languages ( https://upload.wikimedia.org/wikipedia/commons/4/4f/IndoEuro... ). Neither Latin nor Greek grew from Sanskrit but rather each (and many other languages) grew from Proto-Indo-European that was believed to exist somewhere in 4500 to 2500 BC.
