A quotation is a repetition of someone else's statement or thoughts, often used to convey a specific idea or sentiment. It can come from various sources, including books, speeches, or interviews, and is typically attributed to the original author. Quotations are often used in writing and speeches to support arguments or provide inspiration. In academic and professional contexts, quotations are essential for referencing ideas and giving credit to original authors. They can enhance the credibility of a work by showing that it is grounded in established knowledge. Proper citation formats, such as APA or MLA, are used to ensure that quotations are accurately attributed.
