Arduous describes something that is very hard, tiring, or requires a lot of effort, like climbing a steep mountain or studying for a big exam. It often takes both physical and mental strength.
From Latin “arduus” meaning “steep” or “difficult.” The image is of something rising sharply upward, like a hard climb.
An arduous task doesn’t just take time; it feels like hiking uphill the whole way. When you say something is arduous, you’re secretly comparing it to a mountain your body and mind both have to climb.
