Common mistakes when using professional synonyms for ‘support’
Mistake 1: Using ‘advocate’ when you mean ‘endorse’

Correct: “I support the idea, but I cannot lead it right now.”
Mistake 3: Using ‘substantiate’ in casual conversation
Wrong: “Can you substantiate why you are late?” (Too formal for a simple question.)
Correct: “Can you explain why you are late?”
Mistake 4: Using ‘facilitate’ when you mean ‘do’
