earth: [OE] Earth comes ultimately from an Indo- European base *er-. This produced the prehistoric Germanic noun *erthō, ancestor of German erde, Dutch aarde (whence, via early Afrikaans, English aardvark [19], literally ‘earth-pig’), Swedish and Danish jord, and English earth. Related forms outside Germanic include Greek eraze ‘on the ground’ and Welsh erw ‘field’. The word’s basic range of modern senses, ‘ground’, ‘world’, and ‘soil’, all date back to the Old English period. => aardvark
