blank-faced

The term 'blank-faced' is a modern English compound adjective. Its first element, 'blank', originates from the Old French 'blanc', meaning white or shining, which itself derives from a Proto-Germanic root. Over time in English, 'blank' evolved from describing a white surface to denoting emptiness, vacancy, or a lack of marks or expression. The second element, 'face', comes via Old French from the Latin 'facies', meaning form or appearance. When combined with the adjectival suffix '-ed', the literal construction 'having a blank face' creates a vivid descriptor for an impassive, emotionless, or uncomprehending facial expression, perfectly linking the concrete idea of an empty surface to the abstract state of showing no reaction.
