Expert writing Tips
Best practice
When using "are impossible to", ensure that the subject you are referring to is clearly defined to avoid ambiguity. For instance, instead of saying "Mistakes are impossible to avoid", specify "All mistakes are impossible to avoid for beginners".
Common error
Avoid using "are impossible to" in situations where something is merely difficult but not truly impossible. Overstating the difficulty can weaken your argument. Consider alternatives like "are very difficult to" or "pose a significant challenge to" if complete impossibility is not accurate.
