scabbard: [13] English acquired scabbard from Anglo-Norman escaubers. This appears to have been a compound formed from Old High German scār, which usually meant ‘scissors’ but was also used for ‘sword’ (it came from the same base that produced English shear), and the element -berc ‘protection’ (as in hauberk [13], which etymologically means ‘neck-protection’), which was derived from bergan ‘protect’ (a relative of English borough, borrow, bury, etc). So essentially, a scabbard is ‘sword-protection’.
