[7]: The missing word in position 1 (or positions 1-2 if disyllabic) must carry alliteration and have a vocalic onset. Jón Helgason (Hl 1941) suggests an adj. qualifying bróður Agnars ‘Agnarr’s brother’ (æra ‘younger’ or ítran ‘splendid’). While it is likely that the word could have been an adj., the word itself cannot be reconstructed.
