> Every noun has a gender, and there is no sense or system in distribution; so the gender of each must be learned separately and by heart. There is no other way. To do this one has to have a memory like a memorandum-book.
And yet, every German speaker seems to be able to remember this, without evidence of them being better at memorization than others?
As usual, it's easy to forget how hard things are for others when you're the expert. I'm sure Twain never thought about how ridiculously hard many English words are to spell, and how people learning English as a second language struggle quite a lot with it.
But the thing is, with practice, we do learn these things. With practice speaking German, you'll learn and remember the gender of each noun, it simply becomes part of the noun itself. And with practice writing English, you'll learn the spelling - illogical as it is, it simply becomes part of the word itself.
But looking at my language, I'm not so sure how much of this is pure memory. Swedish, like all Scandinavian languages, has four genders for nouns, but only one of them stick out and modify words and sentences. Being a native speaker, I of course know the gender for each noun, and you could argue that I have memorized this. But I can also properly gender new words. I can gender words I've never heard before. I can construct new words, and gender them correctly as well, and have other Swedish speakers independently agree with me on what the gender of this new word is. So clearly there are rules, it's not the case that someone else decided the genders, and then everyone else had to memorize what this person arbitrarily chose.
And I'm pretty sure German actually works the same way.
