Quality, Quantity and Distribution
Categorical propositions can be categorized into four types on the basis of their quality, quantity, and distribution. These four types have long been named A, E, I and O. This is based on the Latin affirmo (I affirm), referring to the affirmative propositions A and I, and nego (I deny), referring to the negative propositions E and O.
