Which word signifies a feeling of extreme annoyance?

The word "exasperated" signifies a heightened level of annoyance, often suggesting that an individual has reached a point of irritation after enduring more than what feels tolerable. This term implies not just a simple annoyance, but a compounded frustration that has escalated over time. It is often used in contexts where someone feels overwhelmed by repeated annoyances or difficulties, thus fitting perfectly to describe extreme annoyance.

In contrast, while "frustrated" might denote a sense of disappointment or dissatisfaction, it does not inherently convey the intensity of irritation that "exasperated" does. Similarly, "annoyed" is a milder term that describes a general feeling of irritation, lacking the depth of extreme annoyance. The word "agitated," while indicative of a state of nervousness or unrest, does not specifically convey annoyance alone, thus making "exasperated" the most precise choice for extreme annoyance.
