Usage Tips — when to use formal vs casual alternatives

Match the synonym to your audience. Use casual options like "so," "totally," and "super" with friends, social media, or informal emails. Choose formal choices such as "truly," "undeniably," or "profoundly" for essays, reports, or professional communication.

Avoid overusing a single intensifier. Rotate synonyms to keep prose engaging. If you rely heavily on adverbs, consider stronger verbs or noun phrases as alternatives (e.g., "smiled broadly" instead of "was very happy").

Test variations: write a sentence with "really" and then try 3 alternatives. Use Rephrasely's Composer at https://rephrasely.com/composer to generate alternatives and compare tones.
