Ginn-

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

ginn- Old Norse word can mean:

ginn-

or perhaps better gínn-, [cp. A. S. gin or ginn = vast, wide; it seems however better to derive it from the verb beginnan, Engl. begin, a word used in all Teutonic languages, except the old Scandinavian tongue, where it is unknown, unless in this mythological prefix]:—only used as a prefix:

ginn-

I. in old mythol. words, great, holy: ginn-heilög (adj. pl.) goð, the most holy gods, the supreme gods, as opposed to Asir and Vanir, the lower gods, Vsp. passim: ginn-regin, n. pl. ‘magna numina,’ Hm. 143, Haustl. 13, in the same sense as ginnheilög goð in Vsp.; in Hým. 4 opp. to tívar (dii); in Alm. goð and ginnregin are distinguished, cp. also Hm. 79: ginnungar, m. pl., seems used in the same sense as ginnregin, whence Ginnunga-gap, n. chaos, the formless void, in which abode the supreme powers, before the creation, Edda, Vsp.: later, in the 11th century, the sea between Greenland and America was called Ginnunga-gap, A. A. 295: Ginnunga-himin, m. of the heavenly vault of Ginnunga-gap, Edda 5: Ginnunga-vé, n. pl. the holy places of the Ginnungar, the universe, Haustl. 15: Ginnarr (Ginnir), m., is a name of Odin, prop. = aetherius, and also used of the eagle, the falcon.
