The flow of novelties in vocabulary, in idiom, even in pronunciation, is now overwhelmingly eastward. We seldom borrow an English word or phrase any more, though we used to borrow many; but the English take in our inventions almost as fast as we can launch them. The American movie, I suppose, is largely responsible for this change, but there are unquestionably deeper causes too. English is still a bit tight, a bit stiff, more than a little artificial. But American has gone on developing with almost Elizabethan prodigality. All the processes of word-formation that were in operation in Shakespeare’s England are still in operation here, and they produce a steady stream of neologisms that he would have relished as joyfully as he relished the novelties actually produced in his time.
