To all who answered this question, THANK YOU! What wonderful words there are out there...I had never thought of "ambidextrously", which is at 14 letters is awfully good. Uncopyrightables is even better at 16. These are words one might even see in real life, depending on one's profession. "Subdermatoglyphic" is more sublime! But thanks for the Wiki link. I am a happy wordsmith now!
