Take “Every human is an animal” and ask different questions.
Quantity: universal, because “every” includes all members.
Quality: affirmative, because animality is affirmed.
Mode of predication: direct, since animal is predicated immediately of human.
Metathetic status: non-metathetic, since neither subject nor predicate contains term-negation.
Recognizing several independent classifications in one proposition is a central analytical skill in logic.
