what does [sic] means?
This little notation means, "Hey, I know this quote looks wrong, but it was that way when I found it, so don't blame me." Maybe the original text used archaic spelling or the original writer just messed up. But the person who's quoting that text is aware of the earlier mistake and wants you to know it.
[Sic] is shorthand for all that, at least to scholarly types.
