词源

From Old French lof. 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.
