It's blinkered to say language is solely for "convey[ing] ones [sic] meaning in the cleanest, most concise way possible."

It is. Good thing I didn't say that. I said:

One should always use the word that conveys ones meaning in the cleanest, most concise way possible.

I didn't say "language." I said "the word."

See, that was me being clean and concise and getting my point across. You, on the other hand, got all loosey-goosey with it and now we have a misunderstanding.

Most of the nonce words in Finnegans Wake don't exist because they are "beneficial to the language". To the contrary: Joyce invented words out of sheer playfulness.

And then he explained them. Or put them in context. Or otherwise used them in a way in which he improved the dialog between himself and his readers. He did not say "that was a Poe" only to have someone else say "What's a poe" only to respond "it's one of several meanings in this article here, I think, there weren't any better links."

You know what's dreary? Pointing out that a word choice is imprecise and then, six layers deep, having someone slap you in the face with Stephen Fucking Fry. [sic] yourself. Have you ever seen [sic] used by anyone who wasn't trying to be a dick to the other person?
