From Middle English myddelerthe, middelerthe; an alteration of earlier middelerd; in turn an alteration of earlier middenerd; from Old English middaneard (“Middle Earth”), variant of middanġeard (“Earth, the world”, literally “the middle yard, enclosure, or realm”) mis- or reinterpreting its meaning, from Proto-Germanic *midjagardaz, ultimately from Proto-Indo-European *médʰyos (“middle”) and *gʰórdʰos (“enclosure”). Cognate with Norwegian & English Midgard (q.v.) and Danish, Norwegian, & Swedish Midgård.
