obstruct

Imagine building with LEGOs, and your little brother keeps putting pieces right where you need to work. He is getting in the way. To obstruct something is to block it or make it harder to move forward. A fallen tree can obstruct a road, and a confusing argument can obstruct clear communication. Sometimes people even obstruct justice by hiding evidence or lying to investigators.

Think of it as putting an obstacle in the path. If you obstruct someone's view, you place something in their line of sight. If you obstruct a plan, you make it harder to carry out. It can be physical, like blocking a doorway, or more abstract, like slowing progress with delays and red tape.

To obstruct means to impede, block, or hinder the free passage of something—whether physically or figuratively. It suggests an interference that makes movement, progress, or understanding difficult. For example: "The protesters obstructed traffic by blocking the highway," or "His constant interruptions obstructed the flow of the meeting."

Obstruct can refer to physical barriers like a fallen branch obstructing a path, but it's often used in more abstract ways. Bureaucratic red tape might obstruct innovation, while misinformation can obstruct clear thinking.

The word carries a sense of interference, though it is not always malicious. Sometimes an obstruction is unintentional—such as a pile of boxes accidentally blocking a hallway. However, obstructing justice—intentionally interfering with legal proceedings or an investigation—is a serious criminal offense.

You might also hear "obstruction" used for something that gets in the way in a more conceptual sense. For example, emotional baggage can be an obstruction to forming healthy relationships, or a lack of data might be an obstruction to completing a report.

So whether it's a physical barrier, a bureaucratic hurdle, or a personal challenge, to obstruct is to create an impediment—something that stands in the way of progress or free movement.
