The compound adjective 'white-bearded' is a transparent construction from native English elements. Its first component, 'white', descends from the Proto-Germanic 'hwītaz', which itself derives from the Proto-Indo-European root 'ḱweyt-', meaning 'to shine' or 'bright', a semantic link preserved in the modern color. The second component, 'beard', originates from Proto-Germanic 'bardaz' and is a common Germanic word. The adjectival suffix '-ed' is a productive feature in English for creating descriptive terms indicating possession of a quality. The logic of the word is entirely literal, directly describing the physical characteristic of having a beard that is white, a trait traditionally associated with advanced age or venerable appearance.
