Expert writing Tips
Best practice
When using "could have been", ensure the context clearly indicates the unrealized or hypothetical nature of the situation. Provide sufficient information to clarify the potential outcome. Example: "The accident could have been avoided if the driver had been more attentive".
Common error
Avoid using "could of been" instead of "could have been". The correct form uses "have", which is often contracted to "'ve" in speech and informal writing, but should be written as "have" in formal contexts.
