orotund \OR-eh-tehnd\ (adjective) - 1 : Clearly and elegantly articulated (speech), sonorous, full of deep, rounded sounds; 2 : bombastic, pompous.

"Miguel's orotund delivery of Lear's monologue carried easily to the back row of the balcony."

Today's word originated as a Latin phrase, ore rotundo "with a round mouth" ore "with the mouth" + rotundo "round." "Os" is the Proto-Indo-European word for "mouth" that hardly changed in Latin. It appears elsewhere most notably in osculate "to kiss." This root also emerged in Russian ustnyi "oral" and ust'je "mouth of a river." Latin, however, harbored a peculiar sound change called 'rhotacism' that sometimes changed [s] to [r]. So, the root of "os" actually became or- in Latin, os "mouth", ore "with the mouth," which is why we also have "oral," "orifice," and today's word. "Rotundus" is related to a series of words referring to rolling and things that roll, including English "roll," German Rad "wheel," and "Tory," which comes from Irish Gaelic toraidhe "robber," a word derived from Old Irish verb for rolling after someone, toir "pursuit." Originally, today's word was used to describe clearly articulated speech, with broadly rounded Os and rolled Rs, speech that rolled trippingly off the lips. However, the melodramatic speech of the orator and stage actor was quickly associated with pretension and theatrical wordiness, hence, its newer meaning.
