Ranked by relevance and common usage.
Keep "keener" 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 "keener" 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 "keener", 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 "keener" or choose a simpler alternative from the closest-match group.

From time to time she fell into a sort of reverie, and when she was quite alone she would reason thus: "I am ill, and yet I do not know my complaint. I suffer, and yet I bear no wound. I feel afflicted, and yet I have not lost any one of my sheep. I burn, although I am seated in the deep shade. How many times have the brambles torn my skin and yet I did not cry? How many bees have pricked me with their stings and yet I was soon cured? Thus that which has now wounded me in the heart must be keener than all those!"
