Old English eorþe “ground, soil, dry land,” also used (along with middangeard) for “the (material) world” (as opposed to the heavens or the underworld), from Proto-Germanic *ertho (cf. Old Frisian erthe “earth,” Old Saxon ertha, Old Norse jörð, Middle Dutch eerde, Dutch aarde, Old High German erda, German Erde, Gothic airþa), from PIE root *er- (2) “earth, ground” (cf. Middle Irish -ert “earth”). The earth considered as a planet was so called from c.1400.

earth (ûrth)
n.
Any of several metallic oxides, such as alumina or zirconia, from which it is difficult to remove oxygen. No longer in technical use.
Earth
(ûrth)

The planet on which we live — the third planet from the sun.

Note: The Earth was formed at the same time as the sun, about 4.6 billion years ago.

Note: It consists of an inner core made of iron and nickel, an outer core of liquid metal, a mantle, and, on the outside, a crust.

Note: The surface of the solid Earth is in a state of constant change as the rock is moved around by the processes of plate tectonics.

Note: On the Earth’s surface, the oceans and the continents form the stage on which the evolution of life takes place. The atmosphere above the surface circulates, producing the daily weather.

(1.) In the sense of soil or ground, the translation of the word _adamah’_. In Gen. 9:20 “husbandman” is literally “man of the ground or earth.” Altars were to be built of earth (Ex. 20:24). Naaman asked for two mules’ burden of earth (2 Kings 5:17), under the superstitious notion that Jehovah, like the gods of the heathen, could be acceptably worshipped only on his own soil. (2). As the rendering of _’erets_, it means the whole world (Gen. 1:2); the land as opposed to the sea (1:10). _Erets_ also denotes a country (21:32); a plot of ground (23:15); the ground on which a man stands (33:3); the inhabitants of the earth (6:1; 11:1); all the world except Israel (2 Chr. 13:9). In the New Testament “the earth” denotes the land of Judea (Matt. 23:35); also things carnal in contrast with things heavenly (John 3:31; Col. 3:1, 2).
