City

A city is a relatively large and permanent settlement, particularly a large urban settlement. Although there are no agreed on technical definitions distinguishing a city from a town within general English language meanings, many cities have a particular administrative, legal, or historical status based on local law — for example an article of incorporation approved by the local cognizant (state) legislature separates towns from city government forms, rights, duties and privileges in Massachusetts — similar distinctions are made across the world, particularly in former colonies of the United Kingdom. Historically, in Europe, a city was understood to be an urban settlement with a cathedral; in later usages, especially in the United Kingdom and parts of Commonwealth of Nations, a city was a settlement with a royal charter.

Cities generally have advanced systems for sanitation, utilities, land usage, housing, and transportation and more. This proximity greatly facilitates interaction between people and businesses, benefiting both parties in the process.

A big city, or metropolis, may have suburbs and regions. Such cities are usually associated with metropolitan areas and urban sprawl, creating large numbers of business commuters. Once a city sprawls far enough to reach another city, this region can be deemed a conurbation or megalopolis.
