What should you do if you’re quoting someone, and that quote has a grammatical error?
Say for example that I’m quoting this line from the American Pregnancy Association:
The term used for a pregnancy that ends on it’s own, within the first 20 weeks of gestation.
The proper way to write this is without the apostrophe. I know that, and you know that, but the Association’s proofreader apparently missed it.
The question is what I should do now: how can I quote this without sounding like I’m the one committing a grammatical error?
