When writing papers, I meet typos/grammatical errors in quotations now and then. Should I correct them, or leave them as they are?

    You should leave quotes as they are. There is always the possibility that the quite is actually correct and you have misunderstood it. If you try to improve a quote, you risk to change it's meaning instead. – Guffa Mar 17 '11 at 7:21

    I read an article in the newspaper today which quoted a scientific expert as saying [nuclear] "fusion" when "fission" was correct in the context. I doubt such an expert would make such a fundamental mistake, so the newspaper must have changed it. So +1 @Guffa. – Nathan MacInnes Mar 17 '11 at 15:13

    @Guffa You did that intentionally, didn't you... – MrHen Mar 17 '11 at 16:28

    @MrHen, nice observation.... – user3812 Mar 18 '11 at 1:08

When quoting, the convention is to quote the text exactly as it appears in the source. It is common to mark a misspelling (or other problematical word) that might be otherwise thought to be an error by you (the quoter) by following it with "[sic]". The word sic (which is from Latin) means "as such", that is, the apparent problem occurred in the original text. The square brackets indicate that the text was added by the quoter. For instance,

Our massage treatments help relive[sic] your pain.

    What if there are numerous problems? Would you still include sic for every occurrence? – CodeNaked Mar 17 '11 at 12:53

    I believe you can include [sic] at the end of a quote. It is passive-aggressively acceptable to flag as many [sic]s as you want individually. – MrHen Mar 17 '11 at 16:30

    Another way to annoy is to put [sic] at the end of a very long and complex quotation... that doesn't actually have any errors. (This can lead to nervous breakdown among obsessive-compulsive grammar snobs.) – Beta Mar 17 '11 at 17:26

Adding corrective braces can be useful for this.

Instead of "He go into the sunset" you could gently correct with "He [goes] into the sunset" .
Instead of "I'm going to do it careful" you can use "I'm going to do it [carefully]."

You can also use "[sic]" if you want to leave the error present, and highlight its presence.

It's also common for brackets to be used to modify the tenses and pronouns of the quoted material to match the new text into which it is nested.

Here's example involving verb tense, from the 'net:

The judge's order "restrain[ed] and enjoin[ed] the further implementation" of the law, including the prevention of Secretary of State Doug LaFollette (D) from publishing the act in the Wisconsin State Journal. TPM

The original had present tense, which was altered by the brackets in the second version:

"I do, therefore, restrain and enjoin the further implementation of 2011 Wisconsin Act 10," Sumi said, according to a transcript. Wisconsin State Journal


The adverb sic—meaning "intentionally so written"—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. Sic is generally used inside square brackets, like [sic], and occasionally parentheses/brackets: (sic).

  • I think in the modern workplace (non-academic) using [sic] tends to make one look 'pompous' (in my opinion). {Almost made several spelling / grammar errors just typing this out}. – JosephDoggie Jun 19 '19 at 12:53

I would caution to be sure it is the error of the author and not the publisher. Always try to track down an original source.
