And we also, from Latin in English, via Latin, we have words like maternity and maternal, all referring to the same idea of motherhood. And this general trend, this T sound, mater or mater, becoming more of a the sound in English, in the Germanic languages, a trend you'll see over and over again. In Sanskrit, you have piter. In Latin, you have pater. And by way of Latin, in modern English, we have words like paternity and paternal. But going through the Germanic languages, you have, once again, that the sound becoming more of a the sound, and you also see this pattern as you go from this Proto-Indo-European, this theoretical language, and especially if you think about relative to Sanskrit, that you have this sound going from a pa to a fa as you go to the Germanic languages. So piter becomes, you could say father.
