tedious

This term describes a specific kind of boredom born from repetition and duration. It suggests a grinding quality where the lack of variety or the sheer volume of a task drains the spirit, often evoking a feeling of mental exhaustion rather than simple disinterest.

While similar to boring, it specifically emphasizes the slow pace and the laborious nature of the activity. It is frequently used in professional or academic contexts to describe bureaucratic processes, data entry, or meticulous manual labor that requires high precision over a long period.
