Self-doubt makes good copy editors. I enjoy thumbing through my Chicago Manual of Style, chasing down the specifics on em dashes versus ellipses. Whenever possible, I’ll sacrifice editing speed for accuracy. It’s fun to learn something new, and it’s horrifying to learn that I’ve had a certain rule wrong forever.
Unfortunately, not everyone is crippled by the need to triple-check their no his or her no their usage when writing or editing. Some don’t know or care about the intricacies of grammar, which is forgivable—almost sweet. Others know and care, but the rules they adhere to were mistaught or are misremembered. The following flash cards detail five little rules that I see broken most frequently by professionals who are fairly certain they know what they’re doing. These flash cards are the product of a year of gentle hounding by Meghan, who wanted to pair boring rules with bangin’ design—something that happens behind the scenes quite often.
