It contains the continents of North America and South America, as well as surrounding islands and waters.

Usage

• The term "Western Hemisphere" is used in geographical, political, and cultural contexts to refer to the part of the world encompassing the Americas.
• It is often capitalized as it is a proper noun referring to a specific region of the planet.

Examples

• Proper noun:

Variants and Related Words

Notes on Meaning

• The Western Hemisphere is defined by longitude, not by continents alone. Therefore, it also includes parts of other continents, such as the westernmost portions of Europe and Africa, and the easternmost tip of Russia (Siberia), though these are minor inclusions. The primary and common understanding centers on the Americas.
• The term is distinct from "the West," which is a broader cultural and political concept that can include countries like Australia and Western Europe, regardless of hemisphere.
