The word is often used to describe journeys, both literal and metaphorical, that demand great effort and commitment. It has become a central term in expressing the human condition when facing life's most demanding obstacles, whether personal, social, or professional.
While "arduous" can describe physical challenges, it is also commonly used to describe intellectual, emotional, and even social struggles. It conveys the idea that even though something may seem overwhelming or impossible at first, it can be overcome with persistence and effort.
