[sic]

Sic – generally inside square brackets, [sic], and occasionally parentheses, (sic) – when added just after a quote or reprinted text, indicates that the passage is just as it appears from its original source. The usual purpose is to inform readers that any errors or apparent errors in the copied material are not from transcription – i.e. that they are reproduced exactly from the original writer or printer. Bracketed sics have also been used in humorous comments and for ridicule, typically by drawing attention to the original writer's mistakes.
