A categorical proposition is a proposition that relates two classes of objects. Categorical propositions contain a subject and a predicate term. The subject term comes first in a standard-form categorical proposition. The predicate term comes second in a standard-form categorical proposition.
A standard-form categorical proposition has a quantity and quality, and a specific distribution method for the subject or predicate term (or both). “Universal” and “particular” refer to the quantity of a categorical proposition. “Affirmative” and “negative” refer to the quality of a categorical proposition. The words “all,” “no,” and “some” are called “quantifiers.” They tell us the extent of the class inclusion or exclusion. The words “are” and “are not” are referred to as “copula.” They are simply forms of “to be” and serve to link (to “couple”) the subject class with the predicate class. If a categorical proposition asserts something definite about every member of a class, then the term designating that class is said to be distributed. On the other hand, if the proposition does not assert something definite about every member of a class, then the term designating that class is said to be undistributed.
