[sic]
From Wikipedia:The Latin adverb sic; "thus", "just as"; in full: sic erat scriptum, "thus was it written")inserted after a quoted word or passage indicates that the quoted matter has been transcribed or translated exactly as found in the source text, complete with any erroneous, archaic, or otherwise nonstandard spelling, punctuation, or grammar. It also applies to any surprising assertion, faulty reasoning, or other matter that might be interpreted as an error of transcription.
From Wikipedia: You can use this template to easily insert a "[sic]" notation. This notation is placed after a point in a quotation that, in both the original text and its quotation in an article, contains either an actual textual error or text that appears to be an error—the problematic text must have been faithfully reproduced as it appears in the original source for using sic to be correct. This usage clarifies that the source of text that might otherwise be taken as an error of transcription.
