While it may look very similar to the noun “prologue,” meaning “a separate introductory section of a literary or musical work,” the verb “prorogue” is completely different. “Prologue” can be broken into two Greek words: “pro,” meaning “beginning,” and “logos,” meaning “saying.” As far as “prorogue,” it’s used today primarily in reference to British parliamentary proceedings. “Prorogue” reaches back through Anglo-French to Latin origins in “prorogare,” meaning “to stretch out or prolong.”
