Etymology
The noun 'lighter' (ignition device) is a straightforward agent noun formation from the verb 'to light', meaning to ignite or set fire. The suffix '-er', of Germanic origin, is commonly used in English to form nouns denoting tools or instruments (e.g., cutter, printer). The verb 'light' itself stems from the Old English 'līhtan', which is related to the noun 'lēoht' (light, brightness), both ultimately deriving from the Proto-Germanic root 'leuhtaz'. The semantic logic is transparent: a lighter is a thing that lights. The separate nautical term 'lighter' (barge) originates from the verb 'to lighten' (to make lighter, to unload), sharing the same root related to weight, thus a vessel that lightens the load of a ship.
