re yesterday's purifies 7bm game
pressurise was played by just under 50% of those playing this game (154 from 339) Even spies had only a few more hits (163)
The word itself is hardly unknown - you hear it in the pre-flight announcements every time you are on an aircraft - 'The air in the cabin is pressurized......'
I know the trend these days is to spell such words with an ...ize ending, but I rather had the feeling that Chi gave both forms equal status. Surely pressurize is not also 'rare'??
