Greekearth, land
About This Root
From Greek gē (earth, land). A combining form almost exclusively used as a prefix: geography (writing about earth), geology (study of earth), geometry (measuring earth — originally land surveying), and geometric. Apogee (farthest from earth) and perigee (nearest to earth) apply the root to orbital mechanics. Modern coinages like geopolitics and geothermal continue the tradition.
