The compound adjective "white-clad" is a transparent combination of two native English elements. "White" originates from the Proto-Germanic \hwītaz, describing the color of light or snow. "Clad" is the past participle of the now largely archaic verb "clothe," stemming from Old English clāð (cloth, garment). The literal meaning, "clothed in white," has remained consistent since its formation. Such descriptive compounds were and remain a productive method in English for efficiently denoting a person's specific attire, often implying a uniform, ceremonial role, or pure appearance.

Structure: white (color) + clad (clothed) - white: From Old English hwīt, meaning the color white. - clad: From Old English clāthod, geclāðod, the past participle of clāðian (to clothe), meaning clothed or covered.
