Etymology

The word noisome originates from the Middle English term noy (annoyance/harm), influenced by Old French and Latin roots. By the 14th century, noisome emerged to describe things that are not just harmful but also revolting to the senses—particularly smell. The suffix -some reinforced the adjective form, solidifying its modern meaning of "disgustingly foul" or "noxious."
