This one really gets to me. It bothers me as much as the “then” and “than” mistakes folks make. At least they are both words. Greatful is not a word. The word is GRATeful as in, “I have GRATitude!” It is great to show appreciation. One can even show great amounts of gratitude being “ever so grateful,” but one cannot be grately greatful.It’s easy to remember. Just think of the root word – GRATITUDE!
