Webster's 1828 Dictionary
PROROGATION
n.[L. 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.
Webster's 1913 Dictionary
PROROGATION
Pro `ro *ga "tion, n. Etym: [L. prorogatio: cf. F. prorogation. ]
1. The act of counting in duration; prolongation. [Obs. ] South.
2. The act of proroguing; the ending of the session of Parliament, and postponing of its business, by the command of the sovereign. [Eng. ]
Note: After an adjournment all things continue as they were at the adjournment; whereas, after a prorogation, bill introduced and nut passed are as if they had never been begun at all. Mozley & W.
