A nice quote, passed on to me by Abi Searle-Jones, who got it from A Word A Day (http://wordsmith.org/awad/):
A mass of Latin words falls upon the facts like soft snow, blurring the
outline and covering up all the details. The great enemy of clear language
is insincerity. When there is a gap between one's real and one's declared
aims, one turns as it were instinctively to long words and exhausted
idioms, like a cuttlefish spurting out ink. In our age there is no such
thing as "keeping out of politics". All issues are political issues, and
politics itself is a mass of lies, evasions, folly, hatred, and
schizophrenia. When the general atmosphere is bad, language must suffer.
George Orwell, writer (1903-1950)
