Etymology
The word 'lighthouse' is a transparent compound formed from two native English elements, 'light' and 'house'. Its logic is perfectly literal, describing a 'house for a light'. The Old English ancestor of 'light', 'lēoht', derives from the Proto-Germanic 'leuhtą', which is ultimately from the Proto-Indo-European root 'lewk-', meaning 'light' or 'brightness'. 'House', from Old English 'hūs', traces back to Proto-Germanic 'hūsą', possibly from the PIE root '(s)keu-', meaning 'to cover' or 'conceal'. The compound elegantly encapsulates the structure's primary function: a building designed to shelter and project a navigational beacon.
