Patchwriting occurs when a novice writer attempts to paraphrase, but fails to properly restate the original statement in their own words. Patchwriting relies heavily on the vocabulary and syntax of the original writing and often involves the writer rearranging words and phrases.
Some institutions consider patchwriting a form of plagiarism, however, the COD Library recommends viewing patchwriting as a novice writing mistake and a learning opportunity for the student writer rather than an act requiring punitive measures.
