Noisome (noy some) It comes from Middle English noysome, from noy - shortened annoyance, alteration of anoi, from Anglo-French anui, from anuier to harass, annoy.
Noisome sounds like it might be a synonym of noisy, but it is not.
Something noisome is disgusting, offensive, or harmful, often in
its smell. Also highly obnoxious or
objectionable as noisome habits. English words annoy and
annoyance are also related to noisome.
