[7-8] í öngvar þröngvar jötna ‘into the confining straits of giants’: It is assumed here that öngr ‘narrow, cramped, confining’ is an adj. and þröng is a f. pl. noun ‘narrowing, straits’ (as with LP: ǫngr, þrǫng f., 2), but it is possible, as Faulkes (2011b, 95 n.) points out, that the reverse is the case, with öngvar as a f. pl. noun, and þröng as an adj. The meaning would be the same in both cases.
