Terrific and Not Frightful

So in checking the spelling of the word while paying a compliment in my last post, I noticed that the first definition of three listed by Merriam-Webster Online for the word "terrific" is "very bad: frightful."

It's a completely understandable etymology, but, lest there be any confusion, when I call something terrific, I don't mean it's very bad. Just so we're clear on that.
