Geez, I can’t even use simple words. Even the word “concept” I find is used in Linguistics with a connotation which is totally different from the way I want to use it. So now I suppose I have to coin a new word for what I meant by “concept word”. Ugh, it’s like the dilemma that early mathematicians had: English symbols had too many built in connotations so they had to use Greek letters for equations to avoid confusion. Oh yeah, I never did find out how they teach Calculus in Greece if the main explanatory text is in Greek. Do they use English letters for the equations? Seems like a simple question, but couldn’t find the answer and I suppose it’s too trivial to put much energy into it. I’ll just assume yes and forget it I suppose.
