Of late, many people have started saying "I'm good" when asked whether they would like more to eat or drink. "Care for another glass of red?" "No, thanks, I'm good." I don't know how this came about. Perhaps "good" here means "in good shape." Perhaps it's a relative of another phrase, "it's all good," which is a way of saying "I'm fine" and is used as a substitute for "you're welcome." (If it replaces another substitute, "no problem," I'm all for it.) Or perhaps it's a short form of "good and," which since the 1880s has meant totally, as in "good and tired" or "good and full."

The "I'm good" construction seems very common in Canada. Which raises the question, if you say "I'm good" when you mean "I'm fine" what do you say when you want to say "I'm good" (as in a child's protestation of proper behaviour).
