Signal phrases let your reader know that you are quoting or summarizing from another source.
When you quote a source, you include the author's exact words in your text. Use "quotation marks" around the author's words. Include signal phrases and an in-text citation to show where the quote is from.
Paraphrasing & Summarizing Sources
When you paraphrase or summarize a source, you restate the source's ideas in your own words and sentence structure. Select what is relevant to your topic, and restate only that. Changing only a few words is not sufficient in paraphrasing/ summarizing. Instead, you need to completely rephrase the author's ideas in your own words. You do not need to use quotation marks.
Always use in-text citations when you paraphrase or summarize, to let the reader know that the information comes from another source. Continue to use signal phrases as well.
