The word 'obstruction' means that there is something blocking or getting in the way of something else. For example, if a tree falls on the road, it becomes an obstruction that prevents cars from passing through. Another example could be a person standing in front of a door, preventing others from entering or exiting. The word 'obstruction' can be used in many contexts, such as in sports when a player is blocking the path of another player or in politics when someone is preventing progress.
