wearisome

This term describes a specific kind of exhaustion that stems from persistence and repetition rather than a single burst of intense effort. It carries a heavy connotation of monotony and psychological drain, often evoking the feeling of a task that seems endless or a situation that saps one's will to continue. While it overlaps with physical fatigue, the word is frequently used to describe mental or emotional attrition. It is more formal than tired or boring, suggesting a profound sense of being worn down by the sheer duration or tedious nature of an experience.
