Expert writing Tips
Best practice
When using "obstruct", ensure the context clearly indicates what is being blocked or hindered. For example, "The fallen debris obstructed the road" is clearer than simply saying "The debris obstructed."
Common error
Avoid using "obstruct" when a weaker term like "delay" or "slow" is more appropriate. "Obstruct" implies a significant impediment, so using it for minor inconveniences can sound hyperbolic.
