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.
As a novice in the history of languages and being k-lingual in a couple of Indian languages and English, the Farsi language is such a delightful stream of discoveries.
Regardless of which k of my languages I restrict myself to, I end up discovering words that are same between Farsi and that language.
I understand that this should not be surprising given their roots in Indo-Iranian languages, the largest branches of Indo-European.
Nonetheless it is delightful everytime I discover a new one by accident.
