Protect meaning before changing form
A successful paraphrase is not measured by synonym count or surface difference. It is measured by whether the rewritten sentence makes the same supported claim. Begin by marking protected elements: citations, names, numbers, units, intervals, technical terms, negation, comparison direction, population, setting, time, modality, and causal status.
Consider this source statement: Study A reported no increase in outcome Y after 12 weeks (Lee, 2024). A safe rewrite must retain the negative finding, the outcome, the 12-week period, and the citation. Changing no increase to reduced, or omitting the time period, changes the claim.
Use a constraint-first workflow
- Extract invariantsList evidence, numbers, relations, and qualifying terms that cannot change.
- State the proposition plainlyWrite the supported meaning without trying to sound polished.
- Rebuild the sentenceChange structure and emphasis while retaining disciplinary terms that carry exact meaning.
- Run a bidirectional checkAsk whether the source entails the rewrite and whether the rewrite adds any unsupported proposition.
Watch for quiet forms of drift
Meaning often changes through small edits. May becomes will. Associated with becomes led to. Some participants becomes participants. Higher than becomes different from. A result limited to one setting becomes a general claim. A citation moves to a sentence containing a new proposition it did not support.
When a passage is already concise, highly technical, or legally fixed, paraphrasing may be the wrong goal. Quote briefly when quotation is justified and permitted, cite the source, or retain the technical wording while rewriting the surrounding explanation. Never paraphrase to conceal dependence on a source.
