Sic is a Latin adverb meaning “thus” or “in this way.” In modern writing, it is placed after quoted material to indicate that any errors, unusual spellings, or odd phrasing come from the original source and were reproduced exactly, not introduced by the author quoting it. It helps readers understand that the author is not endorsing or correcting the quoted wording. Common usages include: sic in brackets or parentheses after a misspelled word, awkward grammar, or other nonstandard language found in the source.
