peroration

The word 'peroration' has a direct lineage from Latin forensic rhetoric. It originates from the Latin verb perorare, meaning "to speak from beginning to end" or "to conclude a speech," which itself is a compound of per- ("through, to the end") and orare ("to speak, plead"). In ancient Roman oratory, the peroratio was the final, climactic section of a speech, designed to summarize arguments and stir the emotions of the audience. Over time, the English term absorbed both the specific technical meaning of a speech's powerful conclusion and, by extension, a more general (and sometimes critical) sense of any lengthy and elaborate formal address.

Structure: per (through) + oration (speech) - per: A Latin preposition meaning "through, thoroughly, to completion." In this word, it functions as an intensifying prefix. - oration: From Latin oratio ("speaking, speech, oration"). It functions as the core noun, denoting the act of speaking.
