SECOND LATIN
apple is a substantia, but redness and sweetness are accidentia existing
in the apple.
2. Materia, forma. Every material thing is constituted of materia
prima and forma. The forma is a determining element of any reality.
All bodily things have in common materia prima. Each thing's forma
is what makes it distinct from every other thing. Forma substantialis
makes a thing a substantia of a precise essential nature. Materia prima
is that which all material things have in common. It never actually
exists except as being "informed" by a forma substantialis.
