Expert writing Tips
Best practice
When using "hard" to describe effort, consider the specific nuance you want to convey. "Difficult" might be more appropriate for complex tasks, while "strenuous" emphasizes physical exertion. Choose the word that best fits the context.
Common error
Avoid using "hard" as a one-size-fits-all descriptor. Be specific about the type of difficulty or effort involved. For example, instead of saying "It's hard," specify whether it's "challenging", "complex", or "requires intense focus".
