eastern hemisphere
LowFormal, Academic
Definition
Meaning
The half of the earth that lies east of the Prime Meridian and west of the 180th meridian; commonly understood to include Europe, Africa, Asia, and Australasia.
A term used in geography, politics, and culture to refer broadly to the continents and nations located primarily in the Eastern Hemisphere, often contrasted with the Western Hemisphere (the Americas). It can imply a shared geographic, historical, or geopolitical context.
Linguistics
Semantic Notes
The term is primarily geographical but carries significant geopolitical and cultural connotations. It is often used in contrast to 'Western Hemisphere'. The division is conventional rather than absolute, as some continents (like Africa) are split by the meridians.
