[3] fenja (f.) ‘bristly one’: This heiti is not used by the skalds. According to Falk (1914b, 100), the word is related to ON tálkfǫn ‘filament, fibre in baleen, whalebone’, i.e. the fibres on both sides of the gums that resemble the tail of a swallow, and he suggests that fenja may denote a type of Viking-Age arrow with split points (see also Kock 1898, 262). Cf. ModIcel. fön ‘fan of a feather’. Fenja is also the name of a giantess in Grott 1/4.
