Dewey (the guy we get the numbering system used in many libraries) was looking to simplify English spelling. From the movement he was part of, we get spellings like tho for though and thru for through. George Bernard Shaw used to mock English spelling with the word GHOTI. This, he pronounced fish as it took the gh from enough (or tough), the o from women, and the ti from nation. As for changing spelling and grammar, that is a very difficult task, as we tend to get pedantic jerks like Samuel Johnson who were so enamored of Latin, that they cobbled up rules like "splitting infinitives is forbidden" because the infinitive form of latin (you may be more familiar with Spanish) verbs is a single word that cannot be split. And some people still get bent by the opening sequence of Star Trek ...to boldly go... omg! a split infinitive!
