[sic] or
(sic) (from Latin sicut for "just as"; see also List of Latin phrases) is a bracketed expression used to indicate that an unusual spelling, phrase, or any other preceding quoted material is intended to be read or printed exactly as shown (rather than being an error) and should not be corrected. It carries two possible meanings: either that an error was made by the person from which one is quoting, but it would be dishonest to correct it, or that it appears to be an error, but is in fact correct. For example, when quoting a person named Sandra Bollock (not the actress Sandra Bullock), the author might write "a local resident, Sandra Bollock [sic] said that . . .". Many people think that "sic" stands for "spelled incorrectly"; this is actually a misconception, although "sic" is often used to point out an unusual or incorrect spelling.
