Ranked by relevance and common usage.
Keep "careworn" 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 "careworn" 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 "careworn", 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 "careworn" or choose a simpler alternative from the closest-match group.
OpenGloss and ConceptNet supply richer edges like generalizations, collocations, and derivations.

At length the long-expected knock was heard. She hurried to the door, and met her husband; a man whose face was care-worn and depressed, though he was young. There was a remarkable expression in it now; a kind of serious delight of which he felt ashamed, and which he struggled to repress.

The effect upon his personal appearance of this wear and tear of his intellect was striking and manifest. The hue of youth and health entirely departed from his cheeks, and he looked so sad and careworn, that it was quite a terrible thing to look upon a young lad so, as it were, upon the threshold of existence, and in whom anxious thoughts were making such war upon the physical energies.
