Wkipedia: A community is a social group of organisms sharing an environment, normally with shared interests. In human communities, intent, belief, resources, preferences, needs, risks and a number of other conditions may be present and common, affecting the identity of the participants and their degree of cohesiveness.

The word community is derived from the Latin communitas (meaning the same), which is in turn derived from communis, which means "common, public, shared by all or many"^[1]. Communis comes from a combination of the Latin prefix con- (which means "together") and the word munis (which has to do with performing services).
