Word Origin and History for shield
n.

Old English scield, scild "shield; protector, defense," literally "board," from Proto-Germanic *skelduz (cf. Old Norse skjöldr, Old Saxon skild, Middle Dutch scilt, Dutch schild, German Schild, Gothic skildus), from *skel- "divide, split, separate," from PIE root *(s)kel- (1) "to cut" (see scale (n.1)). Perhaps the notion is of a flat piece of wood made by splitting a log. Shield volcano (1911) translates German Schildvulkan (1910). Plate tectonics sense is from 1906, translating Suess (1888).

v.

Old English gescildan, from the root of shield (n.). Related: Shielded; shielding. Cf. German scilden.
