Expert writing Tips
Best practice
Ensure that the event following "until" is a discrete point in time or a specific occurrence (e.g., a date, a ratification, or a natural event) to maintain clarity.
Common error
Do not add redundant words such as "at the time when" after the phrase. Writing "remained in effect until the time when the law passed" is wordy; simply use "remained in effect until the law passed" for better flow and impact.
