A Taxonomy of Gradual Change. Note. Terms that are used in multiple categories span the categories or are connected with a dotted line. Groups of similar, but not identical, terms are identified with boxes of the same shape (e.g., variations of “fading” are in rectangles, procedures described as “progressive” are in parallelograms). Terms that did not neatly fit into these groups are on the far right and identified with dashed borders.
