Etymology

The word "shield" traces back to Old English scield, meaning a protective barrier or armor. It shares roots with Old Norse skjöldr and German Schild, all derived from Proto-Germanic skelduz. The term has consistently retained its core meaning of physical or metaphorical protection across Germanic languages. Unlike many modern English words, "shield" is monomorphic—its spelling and meaning have remained intact without separable prefixes or suffixes.
