[3] gim ‘fire’: The word is perhaps a borrowing of OE gimm (from Lat. gemma) ‘gem’ (cf. ON gimsteinn ‘gem’, based on OE gimstān), though the word is never unambiguously used to mean ‘gem’ in Old Norse, only ‘fire’ (and it is never used in prose). Possibly instead the word reflects *ga-im (related to eimr and eimi ‘vapour’; see AEW: gim). See also Note to Þul Elds 1/1.
