Formal vs informal: which synonym fits?
Formal writing: sorrowful, downcast, melancholy, dejected, mournful, despondent, woeful. Use these in essays, reports, business emails, and formal stories.
Everyday writing: unhappy, gloomy, miserable, heartbroken. These work in most sentences and are safe for blogs, school work, and general writing.
Casual speech and dialogue: blue. These sound natural when a character is speaking, but they can sound too informal in a formal essay.
