What does "leading question" mean?

A question worded so as to elicit particular information or a particular answer, as in When are you selling the business? This example assumes that the person is going to sell the business, an action that may not have been established or revealed. This expression originated with a specific meaning in law, that is, “a question that guides a witness toward a desired answer.” In court, this practice is called leading a witness and is forbidden. [Mid-1800s]
