Did you know?

The -but in rebut once meant basically "butt", so rebut's original meanings were "to drive or beat back" and "to attack with violent language". Rebuttals can still be rather violent, as anyone who has watched some heated moments in a presidential debate can testify. The word is often used by lawyers, since the lawyer for the accused or for the party being sued almost always tries to rebut the charges against his or her client; but it's also used in plenty of contexts outside the courtroom.
