Simon Winchester said this quote

No critic and advocate of immutability has ever once managed properly or even marginally to outwit the English language's capacity for foxy and relentlessly slippery flexibility. For English is a language that simply cannot be fixed, not can its use ever be absolutely laid down. It changes constantly; it grows with an almost exponential joy. It evolves eternally; its words alter their senses and their meanings subtly, slowly, or speedily according to fashion and need.
