That's very interesting... but if people are learning to speak the English language using the word "up" in this manner, the instructor should be fired. I would not use the word in any of these statements. In most cases, the word should just be eliminated... in other instances, the wording itself should be changed. But this brings up another word that was pointed out by George Carlin that can be used in any part of a sentence, adv, adj, verb, noun, etc. ... nuf said!
