Emily Dickinson Lexicon

PRO-ROGUE, v.t. [prorōg; Fr. proroger; L. prorogo; pro and rogo. The latter word signifies to ask, or to propose; but the primary sense is to reach, to stretch forward; and this is its import in the derivative prorogo.]

1. To protract; to prolong. He prorogued his government. – Dryden.
2. To defer; to delay; as, to prorogue death. – Shak. [In the foregoing senses, the word is now rarely used.]
3. To continue the parliament from one session to another. Parliament is prorogued by the king's authority, either by the lord chancellor in his majesty's presence, or by commission, or by proclamation. – Blackstone.
