ETYM Old Eng. and French forme, from Latin forma; cf. Skr. dhariman. Related to Firm.
In Greek and medieval European philosophy, that which makes a thing what it is. For Plato, a Form was an immaterial, independent object, which could not be perceived by the senses and was known only by reason; thus, a horse was a thing participating in the Form of horseness. For Aristotle, forms existed only in combination with matter: a horse was a lump of matter having the form of a horse—that is, the essential properties (see essence) and powers of a horse. However, Aristotle, like the medieval philosophers after him, does not make it clear whether there is a different form for each individual, or only for each type or species.
In Platonic philosophy Form is generally capitalized and is synonymous with his use of idea.
In logic, the form of a proposition is the kind or species to which it belongs, such as the universal (“All x are y”) or the negative (“No x are y”). Logical form is contrasted with the content, or what the proposition individually is about.1. A perceptual structure or shape; SYN. shape, pattern.

ETYM Old Eng. mirour, French miroir, Old Fren. also mireor, from (assumed) Late Lat. miratorium, from mirare to look at, Latin mirari to wonder. Related to Marvel, Miracle, Mirador.
1. A faithful depiction or reflection.
2. A polished surface that forms images by reflecting light.
Any polished surface that reflects light; often made from “silvered” glass (in practice, a mercury-alloy coating of glass). A plane (flat) mirror produces a same-size, erect “virtual” image located behind the mirror at the same distance from it as the object is in front of it. A spherical concave mirror produces a reduced, inverted real image in front or an enlarged, erect virtual image behind it (as in a shaving mirror), depending on how close the object is to the mirror. A spherical convex mirror produces a reduced, erect virtual image behind it (as in a car’s rear-view mirror).
In a plane mirror the light rays appear to come from behind the mirror but do not actually do so. The inverted real image from a spherical concave mirror is an image in which the rays of light pass through it. The focal length f of a spherical mirror is half the radius of curvature; it is related to the image distance v and object distance u by the equation 1/v + 1/u = 1/f.
Liquid mirrors using, for example mercury, are formed by rotating the liquid so that gravity and centrifugal forces shape it into a perfect parabola. They have a number of advantages over solid mirrors: they do not sag and so can theoretically be made much larger; they are cheaper, and need no polishing. In 1994 a small number of liquid-mirror telescopes had been built for research purposes.

6. A type or class of product.
Simplified version of some aspect of the real world. Models are produced to show the relationships between two or more factors, such as land use and the distance from the center of a town (for example, concentric-ring theory). Because models are idealized, they give only a general guide to what may happen.
ETYM Latin norma a rule. Related to Normal.
Informal guideline about what is, or is not, considered normal social behavior (as opposed to rules and laws, which are formal guidelines). Such shared values and expectations may be measured by statistical sampling and vary from one society to another and from one situation to another; they range from crucial taboos, such as those against incest or cannibalism, to trivial customs and traditions, such as the correct way to hold a fork. Norms play a key part in social control and social order.
