Definition: To quote means to repeat the exact words of another, with the acknowledgement of the source. Often the word quote is used as a substitute for the word quotation. Strictly speaking, this is incorrect. Quote is a verb and Quotation is a noun. So, in effect, you quote a quotation. Despite that, using quote instead of quotation is so prevalent that it is sometimes considered acceptable. In deference to popular usage, the Quotations GuideSite on About.com uses these words interchangeably.
