This is without a doubt an interesting discussion. Permit me un petit cri de coeur.
Can we dare to dream of a language that would be equal to the hope humanity harbors that, one day, we -- or one of us, at least -- will say The One, The All? I know I am as easily misled as anyone.
Just for fun, I copy down here what Rimbaud had to say, however obliquely, about language. It is genuinely interesting:
"---What's more, given every word is an idea, the day of a single universal language will dawn! Only an academic deader than a fossil could compile a dictionary no matter what the language. Just thinking about the first letter of the alphabet would drive the weak to the brink!
" This language will be of the soul, for the soul, encompassing everything, scents, sounds, colors, thought mounting thought. The poet will define the unknown quantity awaking in his era's universal soul: he would offer more than merely formalized thought or evidence of his march on Progress! He will become a propagator of progress who renders enormity a norm to be absorbed by everyone!
"This will be a materialistic future, you'll see. These poems will be built to last, brimming with Number and Harmony at its root, there will be something of Greek Poetry to them. Eternal art would have its place; poets are citizens too, after all. Poetry will no longer beat within action; it will be before it." From a letter to Paul Demeny, Charleville, May 15, 1871.
And Laura has this to say (Petty Tyrants, Chapter 47, page 323):
"...The greater the number of words for any given object, the more precise a definition can be made about it in terms of content continuum. If there are a thousand ways to say apple, by knowing all the associations, we can access the higher realm of thought from whence the idea of an apple has a deeper meaning for man. In this sense, all languages are necessary because they are all complementary. They all tell us about the extraordinary wealth and diversity and limitless possibilities of the Universe in which we exist. What is more, such study of words enables us to interact dynamically with the surrounding reality itself. Word studies develop hyperdimensional awareness which binds us to higher planes."
Let me add this. One of the best books I have read is Un amore by Dino Buzzati. It is written in that very much gendered language, Italian. It's about an architect, late '40s, who has been working hard and needs some company, a woman. He falls in love with the new girl Signora Ermelinda has on hand and begins the journey with her through hell to a resolution in the Empirean that I don't think would translate out of Italian very well. That's a pity. It is one of the most moving books I've ever read, and for all it's digging down into the revolting vulnerability that the human enigma can hold, one of the most satisfying as well.
I'm going to sit down now and make a list of all the languages I don't know, and I'm going to imagine all the great books I can't read, and have a good cry. And then I will go back to my novel, which is coming along just fine.
