PROROGA'TION, noun [Latin prorogatio. See Prorogue.] 1. Continuance in time or duration; a lengthening or prolongation of time; as the prorogation of something already possessed. [This use is uncommon.] 2. In England, the continuance of parliament from one session to another, as an adjournment is a continuance of the session from day to day. This is the established language with respect to the parliament of Great Britain. In the United States, the word is, I believe, rarely or never used; adjournment being used not only in its etymological sense, but for prorogation also.
