Ranked by relevance and common usage.
Keep "sullenly" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "sullenly" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "sullenly", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "sullenly" or choose a simpler alternative from the closest-match group.

"Past me was a weak, wimpy, ineffectual little thing," Alice stated sullenly, "a total doormat, the kind of person that would let you walk all over her. She was more concerned with being a 'good girl' and getting along with everyone and not making waves than expressing her true feelings." She shook her head, then turned to stare Linda square in the eyes. "But you… you changed all that. And for the better. You got me to brush aside my totally PC façade and just express the inner me."
