Common Mistakes to Avoid
- Using ‘explain’ in very formal writing: In academic papers or legal documents, “explain” can sound too simple. Use “delineate,” “expound,” or “articulate” instead.
- Using ‘elaborate’ when you mean ‘clarify’: “Elaborate” asks for more detail, while “clarify” asks for clearer information. Do not mix them up.
- Using ‘justify’ when you only need to describe: “Justify” implies defending a decision. If you are simply describing a process, use “delineate” or “illustrate.”
- Overusing ‘articulate’: This word is strong and formal. Use it sparingly, or it may sound unnatural.
- Forgetting the audience: A very formal word like “expound” may confuse colleagues in a casual email. Match your word to the situation.
