Origin & History of “shield”
Shield goes back to a prehistoric Germanic *skelduz, which also produced German and Dutch schild, Swedish sköld, and Danish skjoldr. this was probably derived from the Germanic base *skel- ‘divide, split, separate’ (source also of English scale, shell, etc), and hence denoted etymologically a ‘flat piece of wood produced by splitting a log, board’. Shelter is probably descended from a compound formed from shield.
