I hate when people use these words incorrectly.

• Impeach= To make an accusation against. A typical misconception is to confuse it with involuntary removal from office; in fact, it is only the legal statement of charges, paralleling an indictment in criminal law.
• Lynch= To execute without due process of law, especially to hang, as by a mob.
• Irony= an outcome of events contrary to what was, or might have been, expected.
