Paraphrasing is one of the best ways to stay original and pass an online check for plagiarism even though you use ideas expressed by other people.
It won’t be difficult to imagine a situation, when you read academic works of some scholars and come across a brilliant idea you’d like to mention in your own work. There are two methods how to do it: to quote the scholar giving a reference to his/her work or paraphrase the idea and, again, give a reference to the author. As you can see, there’s no other method – plagiarism. It’s not the way out.
