I'm continually surprised at how often the newspapers teach me a new word. This today, in a review, saying a book about the U.N. is

... a narrative so ponderous that it could easily have been crafted by the U.N. itself. Like low swells on a wide sea, Mr. Kennedy's orotund phrases roll on and on.

orotund: 1 (of the voice) resonant and impressive. 2 (of writing or style) pompous.

from Latin ore rotundo ‘with rounded mouth’.

No relation to "fat lip?"
