I'd like to see a dictionary with only words that came from this island in it. Quite small, I should imagine. Add to it, words that have not changed (in pronunciation, spelling, or meaning) since they have been conceived, and it would be even smaller. Language will always evolve. Especially English, whose dictionary comes from such a wide range of sources and with such a vast array of spelling 'rules' (all with exceptions), that it's a wonder anyone manages to learn it...
