Static friction is the resistive force between an object and the surface against it GIVEN THAT the object is not in motion. Once the object is in motion, the friction force is known as kinetic (or dynamic) friction. The static friction force is usually greater than the kinetic friction force (ever notice it's harder to get a heavy object moving than it is to keep it moving?)
Weight, in English usage, is ambiguous. In common usage it's used to describe the "mass" of an object. However, in the scientific community, weight is something much different. For example, a kilogram is a unit of mass, and the weight of a 1kg object is simply the product of the mass and Earth's gravitational acceleration: w = m*g. In English units, this is a bit more complicated, as you have to convert from pound-mass (lbm) to pound-force (lbf) or throw the unit of slugs (1 slug = 1 (lbf*s^2)/ft) into the equation.
Education is learning. Enlightenment is a realization of a new perspective on a situation or of a new approach to a problem. One can lead to the other.
