caliginosity

Apodeictic, muliebrity, mansuetude, even caducity, caliginosity, nitid, agrestic, roborant or vilipend have Latin or Greek roots that are very familiar to me and most high school graduates.

I shall be drawing the Prime Minister's attention in a fairly obscure and abstruse way to the word: 'Amid the global fiscal turmoil, we sought illumination but found only caliginosity.'

Earlier on, in comparing her with Van der Linden and the Zwanziger woman, I have lessened her caliginosity as compared with that of the Leyden poisoner, giving her credit for one less death than her Dutch sister in crime.

I dare not ask the oracles: I prefer a cheerful caliginosity, as Sir Thomas Browne might say.
