Choosing the right synonym

  • Sentence evidence is available for rationalism, so synonym choice can be checked against real usage rather than a flat word list.
  • Ranking signals come from moby, wiktionary, derived_reverse, wordnet, and related lexical sources.

Synonym selection checklist

  • Match the part of speech before comparing meanings.
  • Check whether the synonym changes intensity, formality, or emotional tone.
  • Read the replacement inside the full sentence, not just beside "rationalism".
  • Prefer the clearest word over the most unusual word when writing for speed or comprehension.

When not to replace "rationalism"

Keep "rationalism" 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.

Replacement workflow

1. Preserve meaning

Choose a synonym only if it keeps the core idea of "rationalism" intact in the sentence you are editing.

2. Tune tone

Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.

3. Re-read context

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.

Final fit check

After choosing a replacement for "rationalism", 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 "rationalism" or choose a simpler alternative from the closest-match group.

Tatoeba + Wiktionary

The opinion opposed to mysticism in philosophy is sometimes spoken of as rationalism. Rationalism insists that all our beliefs ought ultimately to find for themselves articulate grounds. Such grounds, for rationalism, must consist of four things: (1) definitely statable abstract principles; (2) definite facts of sensation; (3) definite hypotheses based on such facts; and (4) definite inferences logically drawn.
