|Thank goodness for editors|
And one other thing I always screw up isn't necessarily spelling, but... hyphens throw me for a loop. I either leave them out when they need to be there, or I stick them where they have no business existing. I worked with an excellent editor for my urban fantasy trilogy The Necromancer's Inheritance, and he dinged me on hyphens. A lot. I am hyphen challenged. That should probably actually be hyphen-challenged. But I have no idea because I am horrible at knowing when to use them. I mean, the word hyphenated does not have a hyphen. But the word non-hyphenated does. It's amazing people can communicate in English at all.
