Form, n.
The shape or external appearance of a body; the figure, as defined by lines and angles; that manner of being peculiar to each body, which exhibits it to the eye as distinct from every other body. Thus we speak of the form of a circle, the form of a square or triangle, a circular form, the form of the head or of the human body, a handsome form, an ugly form, a frightful form. Matter is the basis or substratum of bodies; form is the particular disposition of matter in each body which distinguishes its appearance from that of every other body.
