Bloviate
The word, the meaning (from Bloviate.com)
To bloviate is to speak loudly, verbosely, and at great length, without saying much. It's an American word that was used by (and to describe) President Warren Harding, who was known for long, windy speeches. To bloviate is to engage in bloviation [n. blow-vee-AY- shun].
In the early nineteenth century, it was fashionable to create "latinized" words by adding Latin endings to ordinary words, giving them an enhanced sense of importance or formality. From blow (brag, boast) was created bloviate, to describe the extended, self-important speeches of certain political figures.
This word has gone in and out of fashion several times after mostly vanishing for the first half of the twentieth century. It is not found in most dictionaries, but is now heard again in the political arena, where such a word may live for years to come.
