what is predicated
convertibly, but does not signify the essence. If, on the other
hand, it is not predicated convertibly of the thing, it either is or
is not one of the terms contained in the definition of the subject:
and if it be one of those terms, then it will be the genus or the
differentia, inasmuch as the definition consists of genus and
differentiae; whereas, if it be not one of those terms, clearly it
would be an accident, for accident was said' to be what belongs as
an attribute to a subject without being either its definition or its
genus or a property.

Next, then, we must distinguish between the classes of predicates in
which the four orders in question are found. These are ten in
number: Essence, Quantity, Quality, Relation, Place, Time, Position,
State, Activity, Passivity. For the accident and genus and property
and definition of anything will always be in one of these
categories: for all the propositions found through these signify
either something's essence or its quality or quantity or some one of
the other types of predicate. It is clear, too, on the face of it that
the man who signifies something's essence signifies sometimes a
substance, sometimes a quality, sometimes some one of the other
types of predicate.
