SYNONYMS FOR earth
3 Earth, globe, world are terms applied to the planet on which we dwell. Earth is used especially in speaking of a condition of existence contrasted with that in heaven or hell: those who are yet on earth. Globe formerly emphasized merely the roundness of the earth: to circumnavigate the globe. It is now used more like world, with especial application to the inhabitants of the earth and their activities, interests, and concerns. In this sense, both globe and world are more inclusive than earth and are used more abstractly: the politics of the globe; the future of the world; One World.
