The word "obstacle" refers to something that gets in the way or makes something harder to accomplish. It can be a physical object, like a tree blocking a road, or it can be something less tangible, like a problem or difficulty that you have to overcome. For example, if you are trying to learn a new language, you might encounter obstacles like not having enough vocabulary or struggling with grammar rules. It's important to identify and work through obstacles in order to reach your goals.
