Annoy (like the French ennui, a word traced by etymologists to a Lat. phrase, in odio esse, to be “in hatred” or hateful of someone), to vex or affect with irritation. In the sense of “nuisance,” the noun “annoyance,” apart from its obvious meaning, is found in the English “Jury of Annoyance” appointed by an act of 1754 to report upon obstructions in the highways.
