Is there such thing as good change or bad change? Is it even possible to pin an adjective to change? Change is uncomfortable, often unwelcome. It throws one off keel and can be abrupt and painful, but I'm not sure it can be labeled. Looking back, some changes that were painful at the time turned out to be for the better. So would I call that good change? Or bad change? Or would I alter the label as time passes? My obsession with words continues: is there a word for a word to which no adjective should be applied? And if so, what is it?
