I don't know about other writers, but I tend to make words up as I go along. Or use words I'm absolutely certain are words, but Word says differently. Well, screw them. I have the power to add things to my dictionary... so there. =op
Writing this post, I wish there was a function in Word that let you see a list of all the words you've added over the years. Since it doesn't, I'll just try to remember a few so you know what I'm talking about.
batshit - I added this one the other day. As in 'she was batshit crazy'. Sure, I could've said 'bat-shit crazy' or 'bat shit crazy', but it has more impact as one word, I think.
Ginsu - it's a brand name and a cultural reference, so why the heck can't it be a properly spelled word?
shitstorm - who among us hasn't weathered one of those.
writerly - because sometimes it's just easier saying 'I was doing writerly things today' than 'I was writing, editing, working on the querying letter, researching agents, networking (i.e. reading blogs...)'
sunuvabitch - I was saying it this way long before Lily on How I Met Your Mother, and if it's said as all one word, why can't it be all one word?
Of course, not all words are recognized in Word anyway. But as good as Microsoft is, it can't think of everything. And who, in the course of their normal lives' needs to know how heterotopic ossification is spelled? (It's fine with the ossification, just not the heterotopic.) Or djinn? (Genie, yes. Djinn, no.) I add those words as I go - after verifying that I am spelling them right beforehand.
And yeah, I know, some editor somewhere is going to want to string me up by my short hairs someday. When that day comes, I may be swayed because there's like a publishing contract on the line, but for now, I'll just continue making things up as I go along.
What about you? What words have you added to your dictionary?
