the 16 terms which are grouped directly beneath the Classes which are the next most general areas in which problem elements can lie
There are 16 Types in the Dramatica structure, four to each Class. The Classes each represent a different point of view and the Types in that Class represent a more refined exploration of that point of view. In a sense, Types describe the basic categories of what can be seen from a given point of view. Just as Domain level appreciations create genre-like brush strokes in the story structure, Type level appreciations determine the nature of the plot.
