"Setting on edge" is an idiomatic expression that refers to a state of irritability, restlessness, or uneasiness caused by certain actions, events, or situations. This phrase is often used to describe a person's emotional reaction characterized by being easily provoked, agitated, or annoyed.
When something or someone "sets on edge," it means they trigger strong negative emotions, leading to a heightened level of discomfort or tension. This feeling can manifest physically or mentally, causing a sensation similar to having one's nerves or senses heightened or sharpened, as if on the edge of one's seat, ready to react or respond impulsively.
The phrase is derived from the experience of hearing a sharp, high-pitched sound that causes an unpleasant sensation in one's body, literally making one feel as if their nerves were on edge. It can also refer to situations where threatening or uncomfortable circumstances provoke a sense of unease or disquiet in someone.
Moreover, this phrase can be applied in various contexts, such as describing a suspenseful or anxiety-inducing atmosphere, a tense situation, or a person whose behavior, actions, or words cause distress or irritation. It encapsulates the idea of being psychologically or emotionally disturbed by external stimuli, ultimately leading to a state of heightened unease or discomfort.
