Expert writing Tips

Best practice

When using "changes have occurred", ensure the context clearly indicates what has changed and, if relevant, the cause or effect of the changes.

Common error

Avoid using "changes have occurred" excessively in passive voice constructions. Opt for active voice where possible to make your writing more direct and engaging. For instance, instead of "Significant changes have been occurred by the new policy", consider "The new policy has brought significant changes".
