The word 'arduous' means something that is difficult, exhausting or demanding. For instance, if you have to climb a very steep mountain, the climb might be described as arduous. If you are working on a difficult task that requires a lot of effort and concentration, that task could also be called arduous. The term can be used to describe a task that is challenging, taxing or tough. The word is commonly used in formal or academic writing, but it can also be used in everyday conversation. It is important to note that 'arduous' carries a connotation of difficulty, so it's not appropriate to use it to describe something that is easy or simple.
