In Norse mythology, Ginnungagap (“mighty gap”) was the vast, primordial void that existed prior to the creation of the manifest universe. In alternative etymology, linking the ginn- prefix in Ginnungagap with that found in terms with a sacral meaning, such as ginn-heilagr, ginn-regin (both referring to the gods) and ginn-runa (referring to the runes), interprets Ginnungagap as signifying a “magical (and creative) power-filled space”.
Ginnungagap appears as the primordial void in the Norse creation account, the Gylfaginning states:
Ginnungagap, the Yawning Void … which faced toward the northern quarter, became filled with heaviness, and masses of ice and rime, and from within, drizzling rain and gusts; but the southern part of the Yawning Void was lighted by those sparks and glowing masses which flew out of Múspellheim
In the northern part of Ginnungagap lay the intense cold of Niflheim, and to the southern part lay the equally intense heat of Muspelheim. The cosmogonic process began when the effulgence of the two met in the middle of Ginnungagap. – Wikipedia
