Expert writing Tips
Best practice
When indicating that something has existed or occurred for a significant duration, consider restructuring your sentence to use phrases like "for a long time" followed by a verb in the perfect tense (e.g., "for a long time, it has been known") or use alternatives like "for a considerable time".
Common error
Avoid using the phrase "long time has been" directly, as it often leads to grammatically awkward sentences. Rephrase to ensure clarity and correctness. For example, instead of "the problem for a long time has been unsolved", try "the problem has remained unsolved for a long time".
