Paraphrasing is the act of restating someone else's ideas in your own words while preserving the original meaning. Proper paraphrasing goes beyond simply swapping a few synonyms — it requires you to fully understand the source material and then reconstruct the idea using your own sentence structure, vocabulary, and voice. Even when paraphrasing, you must include a citation to credit the original author.
The distinction between acceptable paraphrasing and plagiarism lies in the degree of transformation. If your version closely mirrors the original in structure and wording, it is likely paraphrasing plagiarism (also called patchwork or mosaic plagiarism). Genuine paraphrasing demonstrates that you have internalized the concept and can express it independently, which is a key skill in academic writing.
Follow this method for effective paraphrasing. First, read the original passage carefully — multiple times if needed — until you fully understand the concept. Second, set the source aside and write the idea from memory in your own words. This forces you to rely on your understanding rather than copying the original phrasing. Third, compare your version with the original to ensure you have captured the meaning accurately without replicating the structure.
Fourth, adjust your wording if you find that your version still echoes the original too closely. Change the sentence structure, use different vocabulary, and reorganize the order of ideas. Fifth, add your citation — paraphrased content always requires attribution. Finally, run your text through a plagiarism checker to verify that your paraphrase is sufficiently original and does not trigger similarity flags.
The most common mistake is word-for-word substitution — replacing individual words with synonyms while keeping the original sentence structure intact. This produces text that is technically different but structurally identical to the source, and modern plagiarism checkers with rewrite detection will catch it. Another frequent error is paraphrasing too closely by changing only a few words or rearranging clauses without genuinely restating the idea.
Failing to cite a paraphrased passage is equally problematic. Some writers believe that rewording eliminates the need for citation, but this is incorrect. Any idea that originated with another author requires attribution, regardless of how thoroughly you rephrase it. Additionally, over-reliance on a single source — paraphrasing passage after passage from the same work — can constitute plagiarism even if each individual paraphrase is adequate.
Use a direct quotation when the original wording is particularly important — for example, when analyzing specific language, presenting a key definition, or citing a passage whose precise phrasing carries special significance. Quotations should be enclosed in quotation marks (or formatted as block quotes for longer passages) and cited with exact page numbers.
Paraphrasing is more appropriate when you need to convey the general idea of a source in a way that fits the flow of your own argument. It demonstrates deeper understanding than quoting and keeps your writing in a consistent voice. As a rule of thumb, paraphrase when the idea matters more than the specific words, and quote when the exact words matter. Most academic papers should contain far more paraphrased material than direct quotations.

Traditional plagiarism checkers compare text on a word-for-word basis, which means they can miss paraphrased content that uses different vocabulary. Rewrite detection technology goes further by analyzing the semantic meaning and structural patterns of text. It identifies passages that convey the same ideas as existing sources, even when the wording has been significantly altered.
Plagiarism Detector's rewrite detection feature analyzes your text at a semantic level, comparing the underlying meaning of sentences rather than just matching keywords. This catches synonym-swapped paraphrases, restructured sentences, and passages run through automated paraphrasing tools (so-called "article spinners"). If your paraphrase is too close to the original in meaning and structure, the rewrite detection will flag it in the Originality Report.
The most reliable way to confirm that your paraphrasing is adequate is to run your document through a comprehensive plagiarism checker before submission. Plagiarism Detector scans your text against 4+ billion Internet sources and applies rewrite detection to identify both exact matches and semantic similarities. The Originality Report shows you exactly which passages triggered a match, so you can revise them.
Make this a standard part of your writing process. After completing your draft, run a plagiarism check and review any flagged paraphrases. If a passage is marked as too similar to an existing source, rewrite it more thoroughly or convert it to a direct quotation with proper citation. This final verification step prevents accidental plagiarism and gives you confidence in the originality of your work.
