Formal vs informal: which synonym fits?
Formal writing: intelligent, astute, shrewd, wise, ingenious. Use these in essays, reports, business emails, and formal stories.
Everyday writing: clever, bright, brilliant, gifted. These work in most sentences and are safe for blogs, school work, and general writing.
Casual speech and dialogue: sharp, brainy, savvy. These sound natural when a character is speaking, but they can sound too informal in a formal essay.
Example sentences
- The intelligent student solved the puzzle in minutes.
- Her clever plan saved the team both time and money.
- He gave a shrewd answer that impressed the whole room.
- The wise teacher knew exactly when to speak and when to listen.
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.

Do not use smart in every sentence. Rotate through the table above: use one synonym in the first sentence, a different one later, and keep smart itself for the most important moment. That way the writing stays clear without sounding repetitive.
