[8] langviðrum ‘with long-lasting storms’: This cpd, which here refers to a catastrophic emptying of the world (lang ‘long’ plus viðri < veðr ‘wind, weather’), is used as an adv. (langviðris ‘extremely’) in its only other occurrence in poetry (Þorv Lv 1/5IV). The Mhkv cpd in its apocalyptic sense is found in C16th Icelandic prophetic literature.
