And just to get an appreciation for why these philologists believe this, and this is something when I first saw it really blew my mind a little bit, I'll show you some connections between Sanskrit words, and those of you who might be Hindi, Bengali, or Punjabi speakers, or any of these North Indian languages in India will see the connection to Sanskrit. But what's amazing is how these words are connected to Latin and many of the languages derived from Latin. Some of you Persian speakers might recognize some commonalities, and most importantly, the language we're speaking right now, how it's related to English. And so here's just a sample of some Sanskrit words that have an eerie resemblance to both English and in some cases, Latin words, or in many cases, Latin words. I've just given Latin in a few of them. So the Sanskrit matr, well, in English we have mother, and in Latin we have mater. And we also, from Latin in English, via Latin, we have words like maternity and maternal, all referring to the same idea of motherhood.
