What is a common purpose of using quotes in writing?

Using quotes in writing serves various important functions, one of which is to support or validate arguments. When an author incorporates quotes, particularly from credible sources, it adds authority to their arguments. By providing another viewpoint or evidence from an expert, the author can bolster their own claims and enhance their credibility. This practice not only enriches the text but also demonstrates that the author's ideas are grounded in research or recognized authority, which can be persuasive to readers.

In academic and persuasive writing, this use of quotes is crucial, as it allows the author to engage in dialogue with other voices and perspectives, reinforcing their own argument rather than solely relying on personal opinion. This makes an argument more robust and compelling, encouraging readers to take the author's points seriously.
