Expert writing Tips
Best practice
When writing about durations, be specific with dates or events to contextualize the "twenty-five years" period. For example, instead of saying "Changes happened over twenty-five years", specify "Since the 2000s, significant technological advancements have occurred."
Common error
Avoid assuming a "twenty-five years" automatically equates to a generation in demographic or social contexts. A generation's length can vary, and using it interchangeably might lead to inaccuracies.
