The created -- well, chopped and channeled from English, more like -- language "E-Prime," which builds on the interesting notions of of Alfred Korzybski, dodges faulty or misleading usage of the various forms of "to be"/"is."
Korzybski would be the fellow who explained to Heinlein that "the map is not the territory" and that humans are, perhaps uniquely, time-binding animals. Startin' to sound familiar? Thought so!
One does have to wonder if the Wikipedia entry has been looked over lately by any General Semantics types; the sentence, "This* was developed into the language "E-Prime" by D. David Bourland, Jr. 15 years after his death," has me suspecting otherwise. Either that or he's a zombie.
* "This" being the notion that one ought to be aware of and avoid sloppy or misleading usage of "is."
