I misspell more words nowadays than I did when I was in school, that is for sure. It is probably because I don't read as much as I used to. When you don't surround yourself with words, you forget their spellings. I have been misspelling "Onomatopoeia", "calendar" (I put it as -er at the end for some reason) and "tomorrow" as I want to double up on the m for some reason.
