Fascinating. I speak Bengali and found a bunch of "English names that may also be Bengali words" are not Bengali words. Some of those are Bengali words, but not very flattering.
They are Indo European, not Proto Indo European. Big difference.
Indo European is a language family.
Proto Indo European is the reconstructed hypothetical language that languages in that family descend from.
There are indeed a huge number of cognates between the descendant languages, but due to the linguistic changes and borrowings that have occurred in the millenia that have elapsed since their divergence, there are also a massive number of false cognates between them also, which likely accounts for the non flattering meanings the GGP was referring to.
When people see someone saying that European Persian and Indian are the same family they go dipshit because "how can someone with dark skin have any relations to someone with pale skin".
Should say something about the general view of not few HN readers.
