c. 1400, molestacioun, "action of annoying or vexing," from Old French molestacion "vexation, harassing," and directly from Medieval Latin molestationem (nominative molestatio), noun of action from past participle stem of molestare (see molest). In Scottish law it meant "the harassing of a person in his possession or occupation of lands;" in English common law it came to mean "injury inflicted upon another."
