Common Mistakes to Avoid

1. Using “support” too often. In professional writing, repeating “support” makes your language sound vague. Replace it with a more specific synonym when possible.
2. Using “advocate” when you mean “assist.” “Advocate” is about speaking in favor, not helping with a task. Saying “I will advocate you with the report” is incorrect. Say “I will assist you with the report.”
3. Using “endorse” for informal help. “Endorse” is formal and public. Do not use it for everyday help like “I endorsed my colleague with the presentation.” Use “assist” or “help.”
4. Confusing “facilitate” with “do.” “Facilitate” means to make something easier, not to do it yourself. “I facilitated the meeting” is correct. “I facilitated the report” is wrong if you wrote it yourself.
5. Using “uphold” for general support. “Uphold” is for standards and principles. Do not say “I uphold my team” unless you mean you maintain their ethical standards. Use “back” or “support.”
