Etymology

Origin of tedium

First recorded in 1655–65, tedium is from the Latin word taedium

Explanation

Tedium is the state of being really bored while doing something repetitive. You may loathe the tedium of eating dinner with the family — after all, what is more boring than talking to mom and dad, especially if you could be texting friends? The noun tedium comes from the Latin root word taedere, meaning "to weary of," and that's still what tedium means today: bored and weary of it all. The noun can also mean a tedious period of time — school concerts and assemblies are always two hours of tedium. Tedious is a related adjective form of the word. In order to relieve the tedium of homework, you should pick less tedious tasks, try fencing or painting to add some excitement to the day.
