Ok. Against self-preservation gnawling at me, I'm actually going to post this question: What if you are worried about your own basic skills in grammar? Don't laugh - hear me out. I come from a part of the country that doesn't speak very intelligently, as a whole. I love to read, and I understand vocabulary quite well. I speak normally and rarely feel like my speaking grammar is incorrect. But I know I write with the ghosts of my upbringing inside of my head, and I know there is improper grammar on some fronts. I'm writing my first draft passionately and with feeling; I want to edit my next draft(s) with intelligence. I'm worried that when I go to edit my first draft, I'll miss a lot of those grammar errors. I don't want my novel to be rejected because some editor is sitting there, reading my book and thinking, "Has this person not completed grammar beyond the fourth grade?" What tools are there, other than cracking a grammar book, to finely edit a manuscript for grammatical errors? I realize that my writing style differs from honest to goodness errors. And if I have to rob a fourth grader of his or her english book, I will. But if there are some simpler, more effective ways (like a dummies guide to grammar) of finding grammatical errors, I'd appreciate the heads up.
