Origin & History of “lamp”
A lamp is literally something that ‘shines’. The word comes via Old French lampe and Latin lampas from Greek lampás, which was derived from the verb lámpein ‘give light, shine’ (source also of English lantern). The Greek word originally denoted a ‘bunch of burning sticks, torch’, but in post-classical times it was applied to an ‘oil lamp’. The Old English word for ‘lamp’ was lēohtfœt, literally ‘light-vessel’.
