[4] miðfjǫrnir (m.) ‘mid-helmet’: So B. An otherwise unattested cpd from mið- ‘mid-’ and fjǫr n. ‘life’ or fjǫrnir ‘helmet’ (hence ‘mid-helmet’, i.e. ‘helmet protecting the middle of the body’). Falk (1914b, 152 n. 3) prefers the R, C variant miðfornir lit. ‘old in the middle’, possibly referring to a shield with an old shield-boss.
