To rewrite a selection using different words and expressions, read the original until you understand it fully, set it aside, then write the idea in your own words — changing sentence structure, word class, and vocabulary simultaneously rather than swapping one synonym at a time. A free browser-based tool like the BoldlyType paraphrasing tool can draft a first pass in seconds, but the strongest result comes from combining it with your own judgment.
Paraphrasing is one of the most useful writing skills you can practice, and one of the easiest to do badly. The goal is not just to change a few words — it is to absorb an idea and put it back into your own voice.
Why paraphrasing is harder than it looks
The obvious approach is to swap words for synonyms one by one. That rarely works. Linguists call this patchwriting — making minor substitutions on top of a copied structure. According to Indiana University of Pennsylvania's Center for Scholarly Communication, patchwriting is the most common integrity issue graduate writers face.
The core techniques, one by one
1. Synonym substitution
Replace key terms with words that carry the same meaning. The British Council's guide identifies synonym substitution as the starting point for most rewrites.
2. Part of speech conversion
Change a noun to a verb, or an adjective to an adverb. Original: The growth was rapid. Rewritten: The market grew rapidly.
3. Sentence restructuring
Move the subject, split a compound sentence, or combine two short sentences. Grammarly's paraphrasing guide identifies this as one of the most reliable ways to differentiate your version from the source.
