Sic is a Latin word, originally sicut meaning thus, so, just as that. In writing, it is placed within square brackets and usually italicized — [sic] — to indicate that an incorrect or unusual spelling, phrase, punctuation, and/or other preceding quoted material
has been reproduced verbatim from the quoted original and is not a transcription error. The word sic may be used either to show that an uncommon or archaic usage is reported faithfully or to highlight an
error
, often for the purpose
of ridicule or irony.
