Expert writing Tips
Best practice
Use "had been deteriorated" to emphasize that the deterioration occurred over a period of time before a specific point in the past. This is particularly useful when explaining the current state as a consequence of past neglect or damage.
Common error
Avoid using "deteriorated" alone when you want to stress that the deterioration happened continuously before a certain past event. "Deteriorated" is simple past, while "had been deteriorated" emphasizes a past perfect passive state.
