Origin of luff

  • Middle English lof spar holding out the windward tack of a square sail from Old French probably of Germanic origin

    From American Heritage Dictionary of the English Language, 5th Edition

  • Collins English Dictionary states that this word is ultimately derived from Middle Dutch loef. Ellert Ekwall's Shakspere's Vocabulary: its etymological elements (1903) related this verb and loof instead to the East Frisian verb lofen, lufen, which would make it cognate to the French term lover.
