[3] fyld (f. nom. sg.) ‘pent-up’: Lit. ‘filled’. This adj. modifies æði (f. nom. sg.) ‘frenzy’. It could also be taken with húsfrú (f. nom. sg.) ‘housewife’, in which case fyld bæði grimd og æði ‘filled with both ferocity and frenzy’ (ll. 1-2) must be construed as dat. instr., and l. 1 would be an impersonal cl.: ‘it burned in her breast’ (see Sperber). However, the adj. fyldr ‘filled’ usually takes the gen. case (see LP: fylla). Skj B translates fyld as i fuldt mål ‘in full measure’, but the syntax of that construction is unclear. Sperber takes fyld as an unattested noun ‘fulness’ with æði as a gen. ‘of frenzy’.
