- Check the emotional weight of a word. “Rare” can sound positive, while “strange” can sound negative — pick the one that matches your message.
- Use a thesaurus like Synonymfy as an idea list, not a copy-paste tool. Always choose the word you understand best.
- Read sentences aloud. If a synonym feels forced, try a simpler one instead.
