contiguity

n. touching; proximity, closeness

Contiguity is the characteristic when all parts of one area are in physical contact with every other part of the area. It comes from one of Aristotle's Laws of Association. The Law of Contiguity refers to the fact that things that occur in proximity to each other in time or space are readily associated.
