What's the origin of the term lighthouse?

The term 'lighthouse' originated from the Middle English term 'lighthous' (also spelled 'lightowse' and 'lightous'), which derives from the Old English words 'leoht' (meaning 'light') and 'hūs' (meaning 'house'). This term was first used in the 14th century to refer to a structure that emitted light as a navigational aid for ships. Lighthouses were typically constructed on prominent points of land and utilized various lighting systems to project a visible beam for navigation purposes^[1].
