Think about a triangle. No one ever saw a triangle. It doesn't exist in the real world. Yet when you see some bunch of ink on a paper, or any bunch of matter, you can tell wether it looks like a triangle or not. You can assign triangleness to it, in spite of the fact triangleness doesn't exist in the material reality of things. Triangleness preexists both your mind and any attempt to draw a triangle. That's a form. Squareness or elephantness or goodness are other forms. They are eternal, do not depend on the world, and yet the world shape according them.
