Challenged describes someone facing a difficult test or obstacle that requires effort to overcome. When you're challenged by a hard math problem, it pushes you to think harder and try new approaches. Teachers often challenge students with assignments just beyond their current abilities because that's how people learn and grow.

The word suggests difficulty that's meaningful rather than impossible. A video game that's too easy becomes boring, but one that challenges you keeps you engaged and thinking. Athletes welcome being challenged by tough competitors because it makes them better. When someone says “I accept your challenge,” they're ready to test themselves against a difficult task.

People also use challenged to describe disabilities or difficulties, as in “physically challenged” or “visually challenged.” This usage is meant to sound more respectful than older terms, though many people with disabilities prefer direct language like “blind” or “uses a wheelchair.”

Notice the difference between being challenged and being overwhelmed. A good challenge stretches your abilities but remains achievable with effort. The sweet spot is when something is hard enough to make you concentrate and learn, but not so hard that you give up. That productive struggle, where you're working at the edge of what you can do, is what being challenged is all about.
