Additude, happy mistake

One of the students in the Sunday school class I teach wrote as part of an exercise that one thing he brings to the congregation is a good additude.  I liked the idea of “additude” so much I asked if he spelled it that way on purpose.  It turns out he misspelled attitude. But I intend to adopt it: Additude (n), How a positive demeanor adds something powerful to a group, or a day.
