Which of the following terms translates to "new cities" in ancient Greek?

The term that translates to "new cities" in ancient Greek is indeed "Neopolis." This term derives from the Greek words "neo," meaning "new," and "polis," meaning "city." In historical context, "Neopolis" was often used to designate new urban settlements established in various regions, reflecting a practice of founding cities in areas that could support renewed cultural and economic activities.

The other terms, while related to urban concepts in Greek, have different meanings. "Metropolis" refers to a "mother city," which denotes a significant urban center or the primary city in a region that may have control or authority over others. "Paleopolis" translates to "old city," emphasizing historical significance rather than new beginnings. Meanwhile, "Euripolis" does not have a standard translation in this context; it is less commonly referenced and does not convey the idea of newness associated with urban development.

Focusing on "Neopolis" emphasizes the notion of establishing fresh urban environments, which is central to many historical and contemporary discussions about city planning and development.
