The word bloviate - well, it's obviously either something to do with burping, or it's being sent to oblivion by the James Bond villain Blofeld, isn't it?
Well, it sounds like it!
Sunday Rest: bloviate. This word is almost to do with burping, because it probably comes from the word blow. It means to talk lengthily, especially without having anything worth saying. It first appeared in the mid 1800s.
In the USA the word is associated with US President Warren G Harding (quite often reckoned the worst president ever, even though there is, very obviously, considerable competition) who used the word bloviate to describe spending time doing nothing very much. Sadly one of thing he did do a lot was to go on and on and on about nothing very much, so his special meaning soon switched back to the generally accepted one.
