Re: 1816: "Mispronunciation"

So, does anyone else have any words that they (mentally) pronounced incorrectly because they read them long before they heard them spoken? Not me, but a friend of mine had one that was so good that I chose to adopt it into my general language. Misled pronounced "MY-zelled" I think is soun...

Re: 1791: "Telescopes: Refractor vs Reflector"
