"Tell me if I misunderstand, but I take that to mean "words mean whatever an individual chooses them to mean". That to me is both nonsensical and unrealistic."
Within broad parameters established by cultural usage at a point in time, that is essentially true, IMO. Language is in constant flux, with words acquiring new meanings constantly. When enough people agree on a new meaning it becomes part of the general language, but it always begins with one person. How do you think languages developed in the first place? Think about that for a minute, Ben, and then tell me I am being nonsensical and unrealistic. I have a question for Nick at this point by way of giving a concrete example. I once read that African American slang evolves at a very rapid pace, to the point where words often acquire a different meaning in a matter of months. A more definite example is the difference between Old English and Modern English, which applies to just about any other languge that I am familiar with as well.
