"Substance" here means what something is in itself, its "essence". A hat's shape is not the hat itself, nor is its colour, size, softness to the touch, nor anything else about it perceptible to the senses. The hat itself (the "substance") ''has'' the shape, the color, the size, the softness and the other appearances, but is distinct from them.<ref>This illustration is given in [http://books.google.com/books?ei=DfqWTNTxIpHBswb30Yxb&ct=result&id=4cU9AAAAIAAJ&dq=Catholic+Evidence+Training+Outlines&q=hat#search_anchor Maisie Ward and F.

It was used in the early Middle Ages long before the works of Aristotle were current. 'Substance' in common-sense usage denotes the basic reality of the thing, i.e., what it is in itself. Derived from the Latin root 'sub-stare', it means what stands under the appearances, which can shift from one moment to the next while leaving the subject intact. Appearances can be deceptive. You might fail to recognize me when I put on a disguise or when I become seriously ill, but I do not cease to be the person that I was; my substance is unchanged.
