 Yeah, that's a really good point. It gets even more interesting in other languages which have genders for every single noun. And Lera Barditsky's done that fascinating work showing that French people are more likely to describe a bridge as sturdy and German speakers are more likely to describe it as elegant because in one language it's a masculine noun, in another it's a feminine noun. So maybe all of the talk of gender doesn't derive from language, but does some of it in some cases?
