- Using “fantastic” too formally: In a formal report, “excellent” or “outstanding” is better. “Fantastic” sounds too casual for business documents.
- Confusing “faithful” and “friendly”: “Faithful” means loyal, not just kind. Do not say “a faithful waiter” unless you mean they are very loyal to their job.
- Overusing “fascinating”: This word is strong. Use it only when something is truly very interesting. For everyday things, use “interesting” instead.
- Mixing “fortunate” and “friendly”: These words sound different but learners sometimes confuse them. “Fortunate” is about luck, not personality.
