earth

Earth is our home planet, the third from the sun. Life on earth is possible because of its particular climate and the presence of water.

Earth is the most familiar of the planets, being the one we live on. You can also use the word to talk about the earth you stand on — it's the non-liquid part of our planet, the solid ground. It's also another word for "dirt" or "soil." The Old English root, eorþe also had a double meaning, both "ground or soil" and "the material world" or "the abode of man," as opposed to the heavens.
