Formal vs informal: which synonym fits?
Formal writing: serene, tranquil, composed, collected, placid, unruffled. Use these in essays, reports, business emails, and formal stories.
Everyday writing: peaceful, soothing, still. These work in most sentences and are safe for blogs, school work, and general writing.
Casual speech and dialogue: relaxed, mellow, at ease. These sound natural when a character is speaking, but they can sound too informal in a formal essay.
Example sentences

Notice how the same feeling changes when you change the word: a formal synonym makes a sentence sound serious, a casual synonym makes it sound like natural speech, and a neutral synonym works in both.
