þrymr
nafnorðkarlkyn
1. m. an alarm, noise, freq. in Lex. Poët. of battle: also in poët. compds as, þrym-draugr, -kennir, -lundr, -njörðr, -regin, -rögnir, -svellir, -viðr, = a warrior (cp. Homeric βοην ἀγαθός); in the old lay, Em. 2, for hvat þrymr þar, we read, hvat þrym (dat.) er þar, what din is there? The lost vellum, we suppose, had ‘hvat þrymz þar,’ where z might be the inflexive -r, but was meant to be the personal verb ‘er,’ often written in this abbreviated form above the line; þruma or þrymja, = tonare, is never found in old prose writers or poets; the conclusive reason is that the true idiomatic construction in this case is ‘hvat’ with a dative, and not with a verb (cp. hvat er þat hlym hlymja, Skm.)
2. adj. [A. S. þrym], glorious; this seems to be the sense in Skv. 2. 14; þrymr um öll lönd (frægr um öll lönd, v. l.); although the passage is somewhat imperfect, for the verb is wanting.
