Note to Eil Þdr 7III
[7] fellihryn fjalla ‘the toppling-noise of the montains [RIVER]’: Hryn ‘noise’ is attested neither as a simplex nor as the base-word of a kenning, but the word occurs frequently as the first element of compounds. In these instances the noun hryn- means ‘noise, din, flow, rush’ (cf. the related verb hrynja ‘fall down loudly’). Felli- ‘felling, toppling’ probably refers to the power of the water which threatens to knock the waders off their feet. Here, as in byr markar ‘wind of the forest’ (see Note to ll. 1, 2), the meaning ‘river’ must be inferred from the context.
