A standard-form categorical proposition has a quantity and quality, and a specific distribution method for the subject or predicate term (or both). ... 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.
How many types of categorical claims are there?

What is the significance of determining categorical propositions in standard form?
the quality of a standard form categorical proposition determines the distribution status of the predicate (such that if the quality is affirmative, the predicate is undistributed, and if the quality is negative, the predicate is distributed).
