The OP is glad she bothered with this thread - she finds it all tremendous fun!
The bastardised quote from Cato the Elder is a deliberate joke. As other posters have picked up on, it ties neatly into the general drift of this thread. There is something tragi-comic about the use of barely understood words without a self-subverting dimension.
Mondy, please, youre besmirching the image of pedants and, being one, I take that personally! To have a respect for precision in language is to be applauded and will serve you well. You sound like youre trying too hard though. Its better to allow people to infer your intelligence from the quality of what you say, rather than to shove it down peoples throats by unnecessarily tarting-up how you say it.
As the poster from France has mentioned: even when we spell or pronounce it correctly, were wrong to use the word to describe an outdoor school anyway, so the argument for pedants should really end there.
