Etymology

The word "dark" traces back to Old English deorc, meaning "hidden, obscure, or devoid of light." It shares Proto-Germanic roots (derkaz) with related terms in German (dunkel) and Dutch (donker). The core concept of "concealment" or "lack of illumination" has persisted through its evolution, later expanding metaphorically to represent ignorance or malevolence.
