A metropolis (//) is a large city or conurbation 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. The term is Greek and means the "mother city" of a colony (in the ancient sense), that is, the city which sent out settlers. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation.
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 most commonly metropolises. Although the correct plural is "Metropoles", Latin from the Greek "Metropoleis"
For urban centers outside metropolitan areas that generate a similar attraction at smaller scale for their region, the concept of the regiopolis, short regio, was introduced by German professors in 2006.

In the ancient past, metropolis was the designation for a city or state of origin of a colony. Many large cities founded by ancient civilizations have been considered important world metropoles of their times due to their large populations and importance. Some of these ancient metropoles survived until the modern days and are among the world's oldest continuously inhabited cities.
Using modern criteria, Rome is considered the first ever metropolis, containing one million people around year 1 and an urban culture that included architectural achievements unsurpassed for centuries.
Etymology and modern usage
This 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 suffragan bishops were responsible. This usage equates the province with the diocese or episcopal see.
In modern usage the word has come to refer to a metropolitan area, a set of adjacent and interconnected cities clustered around a major urban center. In this sense, metropolitan usually means "spanning the whole metropolis" (as in "metropolitan administration") or "proper of a metropolis" (as in "metropolitan life", and opposed to "provincial" or "rural").
The concept of a global city (or world city) is of a city that has a direct and tangible effect on global affairs through socioeconomic means. The term has become increasingly familiar, because of the rise of globalization (i.e., global finance, communications, and travel). An attempt to define and categorize world cities by financial criteria was made by the Globalization and World Cities Study Group & Network (GaWC), based primarily at Loughborough University in England. The study ranked cities based on their provision of "advanced producer services" such as accountancy, advertising, finance and law. The inventory identifies three levels of world cities and several sub-ranks (see GaWC study).
A metropolis is not necessarily a global city—or, being one, it might not be among the top-ranking—due to its standards of living, development, and infrastructures. A metropolis that is also a global city is a global metropolis.

In South Africa, a metropolitan municipality or "Category A municipality" is a municipality which executes all the functions of local government for a conurbation. This is by contrast to areas which are primarily rural, where the local government is divided into district municipalities (comparable to a "county" in the US) and local municipalities. There are eight metropolitan municipalities in South Africa. Big cities belonging to a larger urban agglomeration, but which are not the core of that agglomeration, are not generally considered a metropolis but a part of it. The plural of the word is most commonly metropoles.

These functions are seen as key domains for metropolitan regions in developing their performance.
In spatial planning a metropolis is usually observed within its regional context, thus the focus is mainly set on the metropolitan regions. These regions can be mono central or multi central. Eleven metropolitan regions have been defined due to these indicators: Berlin-Brandenburg, Bremen-Oldenburg, Dresden-Halle-Leipzig, Frankfurt-Rhine-Main, Hamburg, Hannover-Braunschweig-Göttingen-Wolfsburg, Munich, Nuremberg, Rhine-Neckar, Rhine-Ruhr (with Cologne/Bonn), and Stuttgart.

Metropolis as a mainland area
In France, Portugal, Spain, and the Netherlands metropolis (métropole (Fr.) / metrópole (Port.) / metrópoli (Spa.) / metropool (Dutch)) designates the mainland part of a country near or on the European continent; in the case of France, this would mean 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 except its colonies (the Ultramar). In France métropole is also used to refer to large agglomerations.
