/ˈnuːsəns/noun, adjective
A person or thing causing annoyance, trouble, or harm
From Latin nuisance (to hurt or harm).
Lineage
The story
In medieval Europe, a nuisance was not merely an irritating neighbor with a leaf blower; it was genuine harm, damage, or injury. The word traveled from Latin nocēre, “to hurt,” through Anglo-French nusaunce and Middle English noysaunce before settling into English nuisance around 1400. By the 1660s, English speakers were applying it to community irritants such as foul smells, pests, and ugly obstructions. English law later made the distinction public versus private nuisance, turning everyday aggravation into a formal common-law category. So when someone calls you a nuisance, the word still carries a faint medieval legal threat: you are not just annoying—you are, linguistically speaking, causing harm.
