E-prime refers to the english language, without the verb to be. I’ve written everything on this website in e-prime, excepting a handful of old articles and stories (A Boy Named Num, Gold Coins For Copper Pennies, and one or two others.)
Indigenous (non/pre-civilization) languages all seem to lack a to be verb. In fact, it may have served instrumentally in helping build hierarchy and specialization. Inevitably you’ll find, that native terms for “hunter” or “runner” come out “he/she hunts” or “he/she runs”. Not labels, but activities. Labeling someone “leader”, “follower”, “mason”, “farmer” requires use of the to be verb, and the concept of static professions. Once again, we want to cross back over that line, from Hierarchy to Family.
A simple web search will reveal much more on e-prime that I don’t need to repeat here. Suffice to say, I consider it more of an experiment, than any kind of dogma. The staff of the College love linguistic puzzles, in any case. And just perhaps, together, we’ll create new language that will bring the world alive again.
