The term "twelve-mile limit" has been used for centuries to refer to a country's territorial waters and economic exclusion zones, where a nation's sovereignty extends 12 nautical miles from its coastline. However, there are several synonyms that can be used to describe this area including the "coastal zone," "maritime zone," "exclusive economic zone," "territorial sea," and the "contiguous zone." Each of these synonyms describes the same concept of a defined area of water that is under the jurisdiction of a country, and extends out from the coast for a specified distance. Understanding the terminology and legal significance of these synonyms is essential for maritime navigation and trade.
