I actually did a paper once, I can't find it now, on how ULTRAFRENCH physically changes the human body for greater speed, strength, and attractiveness. Quite curious stuff.
The mystery of ULTRAFRENCH is both simple and divine. French is mostly French. But English is also mostly French. Québecois either birthed ULTRAFRENCH or developed alongside it (I don't do historical linguistics, and it's still an open question). We all know Québecois is just English speakers trying to speak French, so it just ends up sounding like your Freshman French class. But in ULTRAFRENCH a separate phenomenon occurred. ULTRAFRENCH was, in the beginning, entirely conventional French while also borrowing at least half of itself from English. So by a conservative estimate (since English is 3/4ths French), ULTRAFRENCH is at least 125% French.
Needless to say, the discovery of ULTRAFRENCH wiped away a lot of assumptions that linguists held to be obviously true. How could a language be more than a language? How could it be itself and yet so beyond itself that it tapped into the nether regions of the brain (you know, the 99.9% we don't use) and created a strange system of a sort of interpersonal echolocation?
You see, MRIs suggest that ULTRAFRENCH speakers have at least three conversational layers. Obviously there's body language, which is a complex mix, a bastard, if you will, of Normal English, Canadian, and French. That's one layer. Then there's the spoken/sung/rapped/throat-sung/intoned/whispered/Sprechstimmed side of the language. On the purely spoken level, ULTRAFRENCH has at least as much linguistic density as Ithkuil, but it also has all the airiness and punch of a grammarless language like Chinaese.
The third level is the hardest to measure and study. You see, we can detect rays and beams of energy floating between ULTRAFRENCH speakers if we use certain long-forbidden measurement systems, but we still don't understand the composition of these emissions. Are they some kind of light? Electromagnetic energy? A particle? Something else entirely?
I've never claimed that speaking ULTRAFRENCH endows you with telepathic abilities. That would be preposterous. I'm just saying that ULTRAFRENCH speakers can read each others minds and send thoughts to each other.
Is Sanskrit the best language? The robots tell me so. But they are missing out on an essential part of ULTRAFRENCH. It's not racist to say robots are immune to most forms of not-telepathy and the Force. I have several android friends
Sanskrit might be "technically" "superior" to ULTRAFRENCH on the level of the plain written language. Sure, but it's unfair to compare them because Sanskrit started out as a written language until the ignorant masses started attempting to "speak" it.
But when you consider the triune nature of ULTRAFRENCH, I think it's clear that, at least in spoken communication with non-android participants, ULTRAFRENCH is the best earth-based language. And I think you'll agree that it almost...embodies the triune gods of its founding people. Are Shiva, Vishnu, and Brahma incarnated in every word that drops from an ULTRAFRENCH speaker's enhanced tongue? I can't speak for them, but yes.
Lithuanian still prettier tho IMO
