Perorate is a verb that means to speak in a pompous way.
Our word of the day combines the Latin prefix P-E-R meaning ‘through’ with orare (oh RAHR ay) which means ‘to speak.’ Together, perorate means to speak at great length. Speaking at great length is often done by people who may be considered pompous or arrogant.
