[4] japra: A hap. leg. and the f. form of m. japr, a term for ‘serpent’ known only from this þula (see st. 4/1 below), but cf. ModIcel. japi ‘snake’. The origin and the sense of this word are unclear. The heiti could be related to ModIcel. japla ‘chew’, MLG japen ‘gape’ and mean ‘biting one’ or ‘gaping one’ (AEW: japr, japra; ÍO: japi).
