The categories can be organized into three subcategories by what they predicate about the subject.

1 The predicate is the subject itself.
If the predicate is that which is the subject itself and does not exist in the subject, the predicate is a substance. (Suzanne is a human being.)

2 The predicate exists in the subject.
If the predicate exists in the subject absolut ely as flowing from matt er, the predicate is a quantity. (Suzanne is tall.) If the predicate exists in the subject absolutely as flowing from form, the predicate is a quality. (Suzanne is intelligent.) If the predicate exists in the subject relatively with respect to another, the predicate is in the category relation. (Suzanne is Mary’s daughter.)

3 The predicate exists in something extrinsic to the subject.
If the predicate exists in something extrinsic to the subject and is partially extrinsic as a principle of action in the subject, the predicate is an action. (Suzanne analyzed the data.) If the predicate exists in something extrinsic to the subject and is a terminus of action in the subject, the predicate is a passion. (Suzanne was injured.) If the predicat e exists in something extrinsic to the subject and is wholly extrinsic as a measure of the subject according to time, the predicate is in the category when. (Suzanne was late.) If the predicate exists in something extrinsic to the subject and is wholly extrinsic as a measure of the subject according to place, the predicate is in the category where. (Suzanne is here.) If the predicate exists in something extrinsic to the subject and is wholly extrinsic as a measure of the subject according to the order of parts, the predicate is in the category post ure. (Suzanne is standing.) If the predicate exists in something extrinsic to the subject and is merely adjacent to the subject, the predicate is in the category habiliment. (Suzanne is in evening dress.)
