A quotation is the repetition of one expression as part of another one, particularly when the quoted expression is well-known or explicitly attributed (as by citation) to its original source, and it is indicated by (punctuated with) quotation marks.
A quotation can also refer to the repeated use of units of any other form of expression, especially parts of artistic works: elements of a painting, scenes from a movie or sections from a musical composition.
The rest of this article addresses only written or oral quotations.
Reasons for using quotations
Quotations are used for a variety of reasons: to illuminate the meaning or to support the arguments of the work in which it is being quoted, to provide direct information about the work being quoted (whether in order to discuss it, positively or negatively, to pay homage to the original work or author, to make the user of the quotation seem well-read), and/or to comply with copyright law. Quotations are also commonly printed as a means of inspiration and to invoke philosophical thoughts from the reader.in accounting terms,it is very useful to businessmen
Common quotation sources
Famous quotations are frequently collected in books that are sometimes called quotation dictionaries or treasuries. Of these, Bartlett's Familiar Quotations, The Oxford Dictionary of Quotations, The Columbia Dictionary of Quotations, The Yale Book of Quotations and The MacMillan Book of Proverbs, Maxims, and Famous Phrases are considered among the most reliable and comprehensive sources. Diaries and calendars often include quotations for entertainment or inspirational purposes, and small, dedicated sections in newspapers and weekly magazines—with recent quotations by leading personalities on current topics—have also become commonplace.
Many quotations are routinely incorrect or attributed to the wrong authors, and quotations from obscure or unknown writers are often attributed to far more famous writers. Examples of this are Winston Churchill, to whom many political quotations of uncertain origin are attributed, and Oscar Wilde, to whom anonymous humorous quotes are sometimes attributed.
Deliberate misquotation is also common, though this is often not noticed, usually because the misquotation is better known or because the misquotation better fits a situation. For example, the Star Trek catchphrase "Beam me up, Scotty" did not appear in that form in the original series—likewise, the famous Dirty Harry quotation "Are you feeling lucky, punk?" is actually a rewording of the original dialogue. This differs from misinterpretation, in which an author's words are taken out of context, such as the Nietzsche phrase "God is dead", which is often misunderstood to mean physical death.
