Ellohay!

In yesterday's comics, a query regarding why Earth is named Earth resulted in a rabbit-chasing tale about language development, specifically two languages on earth which were invented on purpose.
Do you know what they are?

My first thought was Pig-Latin which should be enjoyed by all at some point in their life - even if just to share about what some little person is getting for Christmas without them understanding BUT I expect younger brains do the translating easier than isthay olderay indmay - don't get it? Here's a translator! And even a teaching site for those wishing to become master Pig Latin-ers.
Was I right? Was this one?
Nope.

My second guess was the language made popular by the kid's program Zoom (Come on and zooma-zooma-zooma zoom!) called Ubbi Dubbi which I just learned may predate PBS. Gubo Fubigubure. Try singing this at your next birthday party. Bet you could blow out all your candles at the same time!
But it wasn't one of the one's referenced.

There are the languages created by J.R.R. Tolkien for the Lord of the Rings trilogy. For more info on these languages look here, here, there AND here. Extraordinarily interesting & obviously popular (especially since the movies) but STILL NOT one mentioned.

According to Beakman & Jax: "Most languages grow and change as our cultures change. But two languages on Earth were invented on purpose. The first is Esperanto, which was supposed to be the international language...but was a huge flop and is spoken only by a handful of kooks."
Be a kook extraordinaire - learn to speak it!

"The other on-purpose language is Klingon, spoken by Star Trek enthusiasts. Today more people speak Klingon than Esperanto." (Stan mentioned that they are also kooks - LOL)

I expect the number of folks speaking the languages which first came to my mind may outnumber them both! Whadda you think?

Andrew pointed out that both Pig-Latin & Ubbi Dubbi are English based so shouldn't count. I think all newish languages are based on some older languages so it shouldn't matter.
Your opinion?
