"Sic" in a text is a Latin term inserted in brackets after a quoted passage to indicate that a spelling, grammar, or factual error appears exactly as it did in the original source. It signals that the mistake was preserved intentionally, not due to a transcription error.
The term comes from the Latin word sic, meaning "thus" or "so." It's used in scholarly, legal, journalistic, and academic writing to maintain the integrity of a quote while clarifying that the error was not introduced by the person quoting it.
For example, if you're citing a letter that says, "I am very excite about the event," you'd write: "I am very excite about the event [sic]." This tells readers the error is in the original, not yours.
When you include a direct quote that contains a mistake-like a misspelled word, incorrect grammar, or factual inaccuracy-you can preserve the original wording by adding [sic] immediately after the error. This prevents misinterpretation and maintains transparency.
Use [sic] only when the error is visible and not a typo introduced during transcription. If you're unsure whether the original had the error, don't assume. If you correct a mistake, do so without [sic].
Example: A historical document states, "The treaty was signed in 1776, which was the year of American independence." You quote it as: "The treaty was signed in 1776, which was the year of American independence [sic]." The [sic] confirms the original statement is accurate in context-even if the date is wrong, it's preserved as written.
[sic] applies only to errors in the original source. It does not justify poor editing or unverified claims. It's not a tool for mocking or highlighting mistakes in a dismissive way.
There are three main contexts where [sic] appears:
[sic] to show that archaic spelling or syntax is preserved.[sic] when quoting testimony or contracts with known inaccuracies.[sic] when quoting public figures who make factual errors.A common mistake is using [sic] to correct errors in the author's own work. For example, writing "I am very excite [sic]" when you meant to write "excited" is incorrect. [sic] belongs only in quotes from others.
"Sic" is not a synonym for "error," "typo," or "mistake." It specifically marks that the error existed in the original text and was reproduced faithfully. It does not imply judgment or ridicule.
It's also not interchangeable with "as cited" or "quoted from." Those phrases indicate source attribution, not error preservation. Using [sic] adds precision: it says, "This is how it was written."
Another confusion arises between [sic] and [sic!]. The latter is informal and sometimes used in internet culture to mock or emphasize a particularly egregious error. In formal writing, [sic] alone is sufficient and preferred.
Consider a 19th-century newspaper clipping reporting: "The city council voted to build a new bridge, despite the mayor's disapproval." If the original article actually said "despite the mayor's dissaproval," the correct citation would be:
"The city council voted to build a new bridge, despite the mayor's dissaproval [sic]."This preserves the original spelling error while making clear it wasn't introduced by the researcher. According to the Chicago Manual of Style, 17th edition, [sic] is required in such cases to avoid implying a transcription error (Chicago Manual of Style, 2017).
Without [sic], a reader might assume the writer misspelled "disapproval." With it, the reader knows the error was in the source material.
While abbreviations like et al., vs., and etc. are common in academic texts, [sic] serves a unique purpose: it's a corrective marker within a quote. It doesn't shorten words-it explains intent.
Compare [sic] with similar terms:
| Term | Meaning | When to Use |
|---|---|---|
[sic] |
"Thus" - error preserved as-is | After a quoted error in the original source |
| et al. | "and others" - used in citations with multiple authors | In academic references with more than three authors |
| ibid. | "in the same place" - refers to previous citation | When citing the same source consecutively |
| op. cit. | "in the work cited" - refers to previously cited work | When referencing a source already mentioned |
Unlike et al. or ibid., [sic] is not a citation shortcut. It's a signal of authenticity in quotation.
I once edited a student paper that quoted a 1920s government report stating, "The policy was effective in reducing poverty levels." The original report actually said "reducing poverti levels." I added [sic] to clarify the misspelling was in the source, not the student's transcription. The professor later praised the precision, noting that omitting [sic] would have implied a data entry error.
The Modern Language Association (MLA) Handbook, 9th edition, states that [sic] should be used "to indicate that an error in the original text has been preserved." It emphasizes that [sic] must appear immediately after the error and in square brackets (MLA Handbook, 2021).
Similarly, the Chicago Manual of Style recommends using [sic] only when the error is " identifiable" and "not the result of a transcription mistake." It warns against overuse, especially in informal writing (Chicago Manual of Style, 2017).
Always use [sic] only in direct quotations. Never apply it to your own writing. Avoid using it in casual messages, social media posts, or internal notes unless you're following formal documentation standards.
If you're writing for publication, academic submission, or legal documentation, [sic] ensures accuracy and credibility. It's a small mark with big responsibility: it preserves truth, even when it's flawed.
