Signal phrases serve an important role in writing. When you quote someone or paraphrase something you’ve read, you need to attribute the idea or quote to the person who said it. The way you do that is by using a signal phrase.

Think of signal phrases as academic alternatives to “said.” These words and groups of words tell the reader that what he or she is about to read comes from a specific source.
