Patch-writing is a form of plagiarism in which a writer reproduces an idea by keeping crucial words, phrases, or sentence structure while swapping out few parts or making minor changes to the structure. A paraphrase however demonstrates that a writer understands an idea and can explain it in a way that is genuinely his or hers. To paraphrase, read the sentence a few times, think about its meaning, then close the text and write in your own words what you understood from the sentence.
