If you attend a political convention, be prepared to hear a peroration — a long, lofty speech. If the speech really drags on, you might find yourself hoping for its peroration, as peroration can also refer to a speech's conclusion.
Peroration comes from the Latin root orare, meaning "to speak." This ancestry places peroration in the same word family as oration, meaning "a formal speech," and perorate, meaning "to speak at length." A peroration is usually a step above your run-of-the-mill speech, or even a typical oration, as it involves an extended spoken spectacle filled with elaborate and persuasive language.
