Expert writing Tips
Best practice
Use "have formerly been" to clearly indicate a change in status or condition over time. Ensure the context clarifies the original state and the subsequent change.
Common error
Avoid using "have formerly been" when simply indicating a past state without a change. Use a simple past tense construction like "was" or "were" instead if the former state still holds or there is no shift in status.
