What does to be impeached mean?

Answer 1

"Impeachment is the first step in removing an officer from office. The president, vice president, and other federal officers (as judges) may be impeached by the House of Representatives.

The House draws up articles of impeachment that itemize the charges and their factual bases. The articles of impeachment, once approved by a simple majority of the House members, are then submitted to the Senate, thereby impeaching the officer. The Senate then holds a trial, at the conclusion of which each member votes for or against conviction on each article of impeachment. Two-thirds of the Senate members present must vote in favor of conviction. Once convicted, the officer can be removed from office.

Although the Constitution specifies that an officer is to be impeached for high crimes and misdemeanors, impeachment can also occur for misconduct that is not necessarily criminal (as violation of the Constitution).

Because impeachment is the first step taken to remove an officer from office 'impeach' is often used in general contexts to refer to the removal itself, but that is not its specific legal meaning."

In a non-technical sense, Impeach means to question, challenge, or to bring an accusation against.
