The purpose of <u>paraphrasing</u> text is to communicate the author's ideas or main points using your own words. This is an alternative way of referencing the concepts or literary work of other authors without using direct quotation. In academic writing, students are strongly urged to cite their source of information.  If it is too challenging to paraphrase a text, then it is best to directly quote your original source as an in-text citation.  It is also important to include the author's last name and the page number of the text (if using the MLA formatting style).
