Most of the questions I get asked about the English language can be boiled down to this: why is English such an idiosyncratic mess? And why has nobody tried to sort it out?
Well, some people did kind of try. For hundreds of years, English had been a swirling concoction full of Latin, German and French thanks to all the invasions of Britain, plus words English had nicked from other languages, all refusing to behave regularly or obey rules consistently, and riddled with silent Gs.
300 or so years ago, some decided they had HAD ENOUGH.
