Book Definition: Levels of concepts, from most general to most specific, in which a more general level includes more specific concepts. (pg. 272)

In Your Own Words


  • Taking one concept and placing more specific terms and ideas into that one category.
  • a "spider web" of things you know, starting with a general category, and getting more and more specific.
  • A broad term broken down into more specific groups. Concept hierarchies, even those that start with the same large concept, may differ from person to person. Their classification, especially if based on preference, may be different from yours.
  • Think of it like a pyramid. The bottom is more broad so the subject would be vague at first. But, as you go to the top of the pyramid the topic will become more specific and to the "point"
  • Breaking down of a subject to the most specific
  • Taking one thing and breaking it down into smaller more specific catagories
