'cross'(Modern English cross)
Late OE cros (attested only in place-names) and ME cros derive ultimately from Lat crux (oblique stem cruc-) ‘cross’, but there are a variety of possible proximate sources, chiefly: (1) Olr cros (see AEW, Serjeantson 1936: 60, followed by Kastovsky 1992: 319) and (2) ON, represented by OIcel kross, most likely borrowed from it (on other possible sources see de Vries, Mag., Hellquist, Torp, Falk-Torp, Nielsen). AF crosce, cross (variants of the more common croiz) and medieval Lat cros might suggest further possibilities, unless they represent loans of the ME word themselves. Arguments have been made for multiple inputs (thus Diensberg 1997: 459–61, 2006: 51, MED) but it is simpler to suppose a single Hiberno-Norse source (thus e.g. OED, TGD, GDS, Dance 2003: 417–18, Durkin 2014: XX §4.1 n. 6) and this hypothesis is consistent with the circumstantial evidence of place-name distribution in England (see attestation).
