[8] ígull ‘sea-urchin’: Echinus esculentus, ModIcel. ígull. The quantity of the initial vowel ([i:] or [i]) cannot be determined by metre in this line (pace Finnur Jónsson, LP: igull), since a long vowel would result in a line of Type A2l and a short would give a line of Type A2k, both of which are metrical.
