[7] arnkell (m.) ‘old eagle’: A hap. leg. The word is possibly derived from *arn‑kall < *arnkarl, ‘old eagle’, whose second element is the same word as karl m. ‘old man’ (so Lie 1982, 345; cf. also the next heiti). The parallelism of this heiti and the m. pers. n. Arnkell (< Arnketill) must be accounted for by homonymy, unless the eagle-name was taken from a now lost story.
