What does irritation mean?
Irritation is a noun meaning both the feeling of being annoyed by something unpleasant and a physical discomfort caused by a substance or condition. People commonly describe mild anger, impatience, or vexation as irritation, especially when the cause is repeated or irritating. It also has a more technical use for redness, itching, burning, or soreness in the skin, eyes, throat, or another part of the body. The phrase skin irritation refers to a common reaction to soaps, plants, fabrics, or allergens, while eye irritation can result from dust, smoke, or prolonged screen use. The word is useful because it connects ordinary emotional experience with physical sensations that prompt a response. In either meaning, irritation suggests a persistent or recurring source of discomfort rather than a brief, passing feeling.
The state of feeling annoyed, upset, or mildly angry, especially as a result of something unpleasant.
