Word Origin and History for congressional

1690s, from Latin congressionem (from congressus, see congress) + -al (1). Originally sometimes reviled as barbarous, Pickering (1816) quotes an unnamed English correspondent: "The term Congress belonging to America, the Americans may employ its derivatives, without waiting for the assent of the English."
