Expert writing Tips
Best practice
Always use "have fallen" instead of "have been fallen". The latter is grammatically incorrect because "fallen" is already the past participle.
Common error
Avoid using the form "have been fallen". Remember that "fallen" is already the past participle of "fall", so using "been" before it creates an unnecessary and incorrect construction.
