It's not often when reading one of the major national newspapers that I'm stymied by vocabulary in either a news article or opinion piece, but I was recently this week in an opinion article at the WaPo and the word is this: opprobrium. The word could either refer to "a death metal band from Metairie, Louisiana" or "Disgrace arising from exceedingly shameful conduct; ignominy; Scornful reproach or contempt; A cause of shame or disgrace." It's a great word, but I can't ever see using it in casual conversation. Now pontificating from a podium with finger pointing and a stern lecturer of a voice, that's more like it.
Note -- there are a surprising number of news stories using this word. See here.
