History and etymology of hemisphere

The noun 'hemisphere' has its etymological roots in two Latin words: 'hemi,' meaning 'half,' and 'sphaera,' meaning 'sphere.' This combination of Latin terms gives us 'hemisphere,' which refers to half of a sphere, typically divided by an imaginary plane, such as the equator, that passes through the center of the sphere. The concept of a hemisphere has been used in various contexts, including geography and astronomy, to describe regions or divisions of the Earth or celestial bodies.
