# How to Find Synonyms with Claude

Claude finds synonyms and then helps you choose the right one through conversational analysis. Get a list of alternatives, then ask which fits a formal email versus a blog post, which carries positive versus neutral connotation, and which is most commonly used in your industry. The selection process is guided, not just listed.

2. Ask Claude: "Find synonyms for the word important using dictionary-words"
3. Claude returns a list of synonyms
4. Ask: "Which of these works best in a formal business email?"
5. Choose the perfect word for your context
