Natural Examples

Common Mistakes

• Using “support” too often: Repeating “support” in a single email or report makes your writing sound weak. Vary your word choice.
• Using “endorse” for personal help: “Endorse” is for public approval, not for helping a colleague. Say “I will back you” instead.
• Using “uphold” for everyday tasks: “Uphold” is too formal for simple help. Use “support” or “back” for daily work.
• Using “substantiate” without evidence: Only use this word when you have actual data or proof. Otherwise, it sounds exaggerated.

Better Alternatives for Common Situations

• In a job interview: “I champion diversity initiatives in my current role.” (Stronger than “support”)
• In a performance review: “My manager advocated for my promotion.” (More active than “supported”)
• In a project proposal: “This plan is endorsed by the senior team.” (More official than “supported”)
• In a team email: “I will facilitate the training session next week.” (More specific than “support”)

Frequently Asked Questions

It is better to use “endorse” or “advocate” in formal reports. “Back” is fine for internal emails or conversations.

“Champion” is stronger and implies leadership and active promotion. “Advocate” means you speak or argue in favor of something, but not necessarily lead it.

3. When should I use “facilitate” instead of “support”?

Use “facilitate” when you are helping a process, meeting, or activity run smoothly. Use “support” when you are helping a person or idea directly.

No, but it is most common in formal business reports, research, or legal contexts. Avoid it in casual conversation.
