Etymology
Origin of irritation
First recorded in 1580–90, irritation is from the Latin word irrītātiōn- (stem of irrītātiō ). See irritate, -ion
Explanation
An irritation is a situation or action that annoys someone — emotionally or physically. Your off-key singing in the car might be an irritation to the driver, or that poison ivy could be an irritation as well. It's an irritation when you're bothering someone else, and it's also irritation when you're the one feeling irked: "My irritation increased the longer the train sat there, unmoving, with no explanation." The earliest meaning of this word was more physical, a "sore or swollen spot," from the Latin root word irritare, "excite or provoke."
