The compound adjective 'white-faced' is a transparent construction from two ancient Germanic and Romance roots. 'White' descends from the Proto-Germanic 'hwītaz', sharing an ultimate Proto-Indo-European root with words for light and brightness. 'Face' entered English via Old French from Latin 'faciēs', originally denoting 'form' or 'appearance'. The suffix '-ed', of Old English origin, is used to form participial adjectives indicating possession of a quality. The literal combination, 'having a white face', naturally extended to describe the pallor caused by strong emotions like shock or shame, demonstrating a clear metaphorical link from physical description to psychological state.

Structure: white (color) + face (front of head) + ed (adjective suffix) white: From Old English 'hwīt', meaning the color white; the functional role is the descriptive base. face: From Old French 'face', ultimately from Latin 'faciēs', meaning form, appearance, front of the head; the functional role is the noun being modified. ed: A suffix from Old English '-ed', '-od', used to form adjectives from nouns, meaning 'having' or 'characterized by'.
