More contradiction in Wodehouse

"The rain continued to lash down with what you might call indescribable fury ..." (P.G. Wodehouse. 2008. The World of Jeeves. Arrow Books, p. 454)

Well, yes, you might call it indescribable, but that doesn't describe the fury with which the rain lashed down in any specific way! Of course, it's a play on words, indescribable meaning both 'what cannot be described' and 'extreme'.

It takes someone of the indescribable wit of Wodehouse to turn the self-contradictory word indescribable into an almost indiscernible little language joke.
