[3] Gnissa: A hap. leg. Finnur Jónsson (1934-5, 306) connects the name with hnissa f. ‘ill flavour’, but cf. ModNorw. gnisse ‘rub, squeak, creak’ and ModSwed. dialectal gnissa ‘puff, shout’. According to de Vries (AEW: Gnissa), the name is most likely related to the weak verb gniða ‘rub’, hence perhaps ‘one who rubs’. The C variant, Grísla, is also a hap. leg. (for a possible meaning of that word, cf. ON gríss m. ‘pig’ and ModIcel. gríslingr ‘piglet’).
