Expert writing Tips
Best practice
Place the phrase immediately before the noun it modifies to ensure clear attribution of the non-formal status.
Common error
Do not assume "an unofficial" always implies something illegal. Many unofficial actions are perfectly legal but simply exist outside of formal organizational channels. If you mean something is prohibited, use "an unauthorized" or "an illegal" instead.
