[4] fjöld* (f. sg.) ‘multitude’: All mss have fjöldr. Jón Helgason printed the reading from 721 without comment. The word fjöldr cannot be found in any dictionary and is emended to fjöld here. Konráð Gíslason (1846, 76-7) pointed out that occasionally scribes added <r> before or after <ð> due to the similarity of the phonemes. That might be the case here.
