Common Mistakes When Using Smart Synonyms

1. Calling someone “cunning” as a compliment. Cunning often implies deceit — use “clever” or “resourceful” for a safe compliment.
2. Mixing up “clever” and “wise”. Clever solves puzzles fast; wise makes good life decisions. They are not the same. Grammarly’s guide to synonyms stresses matching each word’s exact shade to your context.
3. Using “brainy” in formal writing. Brainy is playful slang — switch to “intelligent” or “knowledgeable” in essays and reports.
4. Throwing “genius” at ordinary competence. Genius means exceptional, once-in-a-generation ability. Save it, or it loses all power.
