Inns of Court

See “ Inn .” In Quad. This is not altogether thieves’ slang, though the gipsy word for prison is quaid . Boys at our public schools say they are “in quad” when they are confined to their own quadrangle. The phrase became popular in connection with a prison when debtors were confined in the Fleet, the Marshal sea, and White cro Street, because they were free to receive visitors in the exercise court or quadrangle.
