[1] Gapþrosnir: An obscure heiti. Falk (1924, 11) believes that this name describes Óðinn as an enchanter or seiðmaðr ‘sorcerer’ and that its original form was *Gap-þrosknir, in which the second element is derived from the m. noun þroski ‘maturity, manhood’ or from the adj. þroskr ‘vigorous, mature’ (cf. Þrór in st. 8/4 below). According to him, the first element is related to ModIcel. gapi ‘magic sign’; cf. such magic signs as gapaldur ‘magic sign’, angurgapi ‘grief-sign’ (to cause loss of cattle), veðurgapi ‘wind-sign’ (to evoke a storm). However, since gapþrosnir is also mentioned among pejorative terms for ‘man’ in SnE (SnE 1848-87, II, 496; cf. CVC: gap-þrosnir = gapi ‘a rash, reckless man’), Finnur Jónsson (LP: Gapþrosnir) surmises that Óðinn’s name may be the same word, although he admits that the meaning of the second element ‑þrosnir is unclear (perhaps from þrusk n. ‘noise’). Alternatively, ÍO: gapþrosnir connects the second element with ModIcel. þrusa ‘prattle’ or with ON þrasa ‘talk big, make a bold show’ (cf. CVC: þrasa), although it is difficult to explain the vowel in the latter case. As an Óðinn-heiti the word does not occur elsewhere.
