I've been collecting odd spellings. Maybe because I read so much, I'm a pretty good speller. But English phonetics works against my students.
Take, for example, the kid who want to spell "true" with a "ch." Sound it out--that actually makes sense "Chuh-roo," he said, and I couldn't argue.
Or the kid yesterday who wanted to spell pizza with a "t." "Peet-za," he said, and he had a point.
Me? I was always tripped up as a kid by "visit." For some reason, that extra "i" always looks weird to me.
So what unusual words can you just NOT spell?
