Esperanto

[Rusty]

It's the name of a language. You'd use it to make reference to that language.

E Interlingua (http://www.youtube.com/watch?v=DRD8HsY1kJI)?

Interlingua is a great idea. I'd love to have a good conversation about constructed languages. The idea seems so great as I'm trying to learn a language.

[CrOtALiTo]

Yes, you can use it in English, for example:

Esperanto is a constructed language, created in 1887 by L. L. Zamenhof.

What up! David.

Thank you for the clarification.
