which is a significant economic, political, and cultural center for a country or region, and an important hub for regional or international connections, commerce, and communications. A big city belonging to a larger urban agglomeration, but which is not the core of that agglomeration, is not generally considered a metropolis but a part of it. The plural of the word is ''metropolises'', although the Latin plural is ''metropoles'', from the Greek ''metropoleis'' (). For urban centers outside metropolitan areas that generate a similar attraction on a smaller scale for their region, the concept of the regiopolis ("regio" for short) was introduced by urban and regional planning researchers in Germany in 2006.

Etymology

Metropolis (μητρόπολις) is a Greek word, coming from μήτηρ, ''mḗtēr'' meaning "mother" and πόλις, ''pólis'' meaning "city" or "town", which is how the Greek colonies of antiquity referred to their original cities, with whom they retained cultic and political-cultural connections. The word was used in post-classical Latin for the chief city of a province, the seat of the government and, in particular, ecclesiastically for the seat or see of a metropolitan bishop to whom

s were responsible. This usage equates the province with the diocese or

. In a colonial context, it is the "mother city" of a colony, that is, the city which sent out settlers. The word has distant roots in the colonial past of Ancient Greece with first usage in Middle English around the 14th century. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation.

Metropolis as a mainland area

In France, Portugal, Spain, and the Netherlands, the word ''metropolis'' (''métropole'' (Fr.) / ''metrópole'' (Port.) / ''metrópoli'' (Spa.) / ''metropool'' (Dutch)) designates the mainland part of a country situated on or close to the European mainland; in the case of France, this means France without its overseas departments. For Portugal and Spain during the Spanish Empire and Portuguese Empire period, the term was used to designate Portugal or Spain minus its colonies (the ''Ultramar''). In France ''métropole'' can also be used to refer to a large urban agglomeration; for example, "La Métropole de Lyon" (the Lyon Metropolis).
