Re: Get it right!
The use of 'refute' to _apparently_ mean 'deny' is (it seems to me) a recent change in language that has been popularised by politicians, who have been loudly 'refuting' accusations for many years. They do this so that if the accusations are proved to be true then they can always say, truthfully, that they never denied it. People have been too lazy to look the word up to establish its meaning and so this incorrect use propogates. Politicians may not be smart, but they're smarter than the average person and they're full of feral cunning.
(A similar thing happened with the word 'obviate', where people said things like, " this new gadget obviates the need to .....". If you know what the word 'obviate' means, then you'll realise what is wrong with that.)
