Expert writing Tips
Best practice
Use "is then open" to clearly indicate that something becomes accessible or available only after a specific condition has been met or a particular event has occurred. For instance: 'Once the payment is processed, the download link is then open.'
Common error
Avoid using "is then open" when the opening or availability is not directly contingent on a preceding event. Saying 'The store is then open' without a prior condition implies it's always open or the opening is not sequential. Instead, use phrasing like 'The store is open' or 'The store will be open' to avoid this misinterpretation.
