Obstruction refers to the act of blocking or hindering something from moving forward or being completed. This can happen in various contexts, such as in a physical space where an object, like a fallen tree, prevents a vehicle from passing. In legal terms, obstruction can involve interfering with the process of justice, such as when someone refuses to provide information to authorities. In everyday life, obstruction can also occur in communication. For example, if someone interrupts a speaker, they are obstructing the flow of conversation. Understanding obstruction helps us recognize barriers, whether they are physical, legal, or social, that can prevent progress or understanding.
