impede

This term describes the act of creating an obstruction that slows progress without necessarily stopping it entirely. It carries a clinical or formal tone, often used in professional, legal, or technical reports to describe delays caused by external factors or systemic bottlenecks. While similar to "block," which suggests a complete halt, this word emphasizes the friction or resistance encountered during a process. It is frequently applied to abstract concepts like justice, progress, or investigations, as well as physical movement through a space.
