Did you know that the alphabet used to contain at least ten more letters than it does now? Me neither.
I knew about the long S although my brain started to short circuit a bit when he got into explaining its usage rules, but the rest of these were new to me. And try as I might, I doubt I’ll ever be able to stop pronouncing it “yee” just because it sounds so neat.
Oh, and if we ever start dropping letters again, let me be the first to say C ya later. I’ve never been able to think of a thing that C does that can’t be accomplished with either S or K.
