I like spelling reform a little bit, but I like etymology more. Knight tells us about Middle English knyght, from a time when they had actual knights riding around, and they pronounced every letter in the word, same as with its Germanic ancestor knecht. Sophistry has a ph because it's Greek and that represents the letter phi, which really was pronounced that way, an "aspirated voiceless bilabial plosive" like spitting. So you get historical context, Germanic knights, Greek Sophists (originally teachers of excellence and virtue). Then there's a bunch of words that break the customary i-before-e rule: deceive, conceive, perceive, receive. By putting the e before the i, those are all telling us the same thing about Norman French grammar, but I forget what,* and whatever it was it's a grammatical rule that we never even used in English. So I'd be happy for that one to be reformed. I guess I support slight change.

* I think it's distinguishing the present tense from the imperfect, in the subjunctive mood. Maybe.
