what's (sic) mean
(sic) (Latin for thus) 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.
DEFINITION of 'Standard Industrial Classification - SIC Code'. A standard series of four-digit codes created by the U.S. government in 1937 for categorizing business activities. In 1997, the use of SIC codes was replaced in most (but not all) capacities by a six-digit code called the North American Industry Classification System (NAICS).
