The Long and Uneventful History of Tedious

Words frequently change their meanings, and some even will go from meaning one thing to meaning something almost opposite (such as nice, which in its earliest use meant "lewd, wanton, dissolute"). Tedious is not one of these words; its meanings may have shifted over the centuries, but they have always had something to do with irksome, boring, or overlong things. The word comes from the Latin taedēre, meaning “to disgust or weary.” Tedious has been in use since the 15th century and has been included in hundreds of dictionaries, although perhaps none have rendered so poetic and succinct a definition as Nathaniel Bailey’s entry in his 1756 New Universal Etymological English Dictionary: “Wearisome by continuance.”
