A quotation is the repetition of a sentence, phrase, or passage from speech or text that someone has said or written. In oral speech, it is the representation of an utterance that is introduced by a quotative marker, such as a verb of saying. For example: John said: "I saw Mary today". Quotations in oral speech are also signaled by special prosody in addition to quotative markers. In written text, quotations are signaled by quotation marks. Quotations are also used to present well-known statement parts that are explicitly attributed by citation to their original source; such statements are marked with quotation marks.
