[1] hamðir (m.): The meaning of this heiti is uncertain. It is perhaps derived from hamr m. ‘skin’ (so AEW: Hamðir; cf. CVC: hamr ‘esp. the skin of birds flayed off with feathers and wings’) and ‑þér (cf. runic þewaʀ ‘servant’) used as a second element in personal names (cf. the legendary hero Hamðir < Hamþér). This explanation is problematic, however, because ‘genuine’ names with ‑þér as a second element are usually old, and it is doubtful whether the word retained its original meaning in later, made-up words (see AEW: þér 3). Heimþér and gamðir ‘amusing one’ (ll. 3, 5 below) have the same second element. Alternatively, Falk (1925a, 239) suggests that this hawk-heiti could have been derived from a mythical pers. n., based on beliefs in the Norse gods’ abilities to shape-change (e.g. valshamr ‘falcon shape’ owned by Frigg and Freyja; Skm, SnE 1998, I, 2, 24, 30). Another possibility is that the word was related to the weak verb hemja ‘restrain’ and meant ‘tamed one’ (for details, see ÍO: hamðir). As a heiti for ‘hawk’ the word does not occur elsewhere.
