Here's a usage question. I need to put a header on a web page. Which should I choose? A. Dos and Don'ts B. Do's and Don'ts C. Do's and Don't's I searched for all three using the Google search engine to survey common practice and got the following results: A. 136,000 web sites B. 157,000 sites C. 8,850 sites I also got 17,200 sites with "Do's and Dont's" and 4,050 with "Dos and Donts." Since I'm assuming the use of apostrophes to mark contractions, I'm ignoring these last two. My inclination accords with the plurality. I favor B, but a colleague of mine favors C. I'd like informed advice from y'all. My reasoning for favoring B, even though A and C are internally consistent in their use/nonuse of apostrophes, is this: Although apostrophes are generally not used for plurals, an exception is made when punctuation is needed to prevent confusion, as in: A's are hard to get from Prof. Gradgrind. You sing the do's and re's, and I'll sing the mi's and fa's. So I lean toward B. The plural of Do needs an apostrophe so it doesn't look like Dos. The plural of Don't doesn't. What do you think? Citation of authority is especially welcome.
