egg-white

The compound 'egg-white' is a transparent English formation, combining two native Germanic roots. The word 'egg' itself entered mainstream English from Old Norse, supplanting the native Old English term 'ǣg'. The element 'white' descends from the Proto-Germanic 'hwītaz', meaning bright or shining, which itself derives from the Proto-Indo-European root 'ḱweyt-', meaning to shine or be bright. The logic of the compound is purely descriptive, naming the part of the egg by its most notable characteristic—its color when cooked—even though in its raw state the substance is clear. This straightforward naming convention reflects a practical, observational approach to terminology.
