I think there are lots of words I probably mispronounce because I only ever read them or write them but never or rarely use them conversationally.
I've also always tended to think that people who misspell (is that how you spell misspell?) are just spelling logically, whereas the spelling of the English language isn't logical.
The reason why people often make mistakes here is that as far as I know their isn't any spell or grammar check buttons here at this website. I don't know why that is, but I think their should be at least a spell check button on The IRC. I know it would certainly cut down all of the spelling mistakes made on some of the posts.
To Make is one of those verbs where, when used in the third person singular, you'll want to add an S to the end of it. Give it a try, It makes no sense. It is tricky. I Make, You Make, He/She/It Makes.
