Expert writing Tips

Best practice

When describing a transformation, pair "has once been" with contrasting information about the current state to highlight the extent of the change.

Common error

Avoid using "has once been" when describing a state that has gradually evolved over time. Use it to define a specific transition point, not to describe continuous evolution. For example, if a company slowly declined, it's better to say it "used to be" successful, rather than using "has once been".
