[3] grákollur ‘grey-skull’: Koll(u)r ‘head’ can denote an animal without horns. The corresponding f. noun ‑kolla ‘female animal without horns’ is often combined with terms for colour (cf. svartkolla ‘black ewe’, gulkolla ‘yellow ewe’, etc.). Earlier eds (except Jón Þorkelsson 1922-7) omit the excrescent [u] in ‑kollur, which makes the line hypometrical. See Note to st. 13/5.
