irritation

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."
