[6] eggjumskarpi (m.) ‘edge-sharp one’: From the dat. pl. of egg f. ‘edge’ and the adj. skarpr ‘sharp’. The C variant ‑skarði is derived from skarð n. ‘notch’ or the adj. skarðr ‘cut, hacked, notched’; hence either ‘one with cutting edges’ or ‘one with cut edges’ (see also skarðr ‘notched one’, st. 5/8).
