Expert writing Tips
Best practice
Use "unfastened" when describing the action of releasing or detaching something that was previously secured. For clarity, specify what was unfastened (e.g., "unfastened the seat belt" rather than just "unfastened").
Common error
Avoid using "unfastened" in overly abstract or metaphorical contexts where a more fitting verb like "released", "detached", or "freed" would be more appropriate. "Unfastened" is best reserved for physical connections.
