"Dos and Don'ts" or "Do's and Don'ts"?

We're happy to introduce the first in a series of tips on usage and style from Grammar Girl, a.k.a. Mignon Fogarty. First up: how do you punctuate do and don't when the words are pluralized?

What's the Trouble? The spelling of do's and don'ts is inconsistent.

Generally, you don't use apostrophes to make words or abbreviations plural (e.g., CDs, 1970s, hats), but English has a few exceptions. For example, you can use apostrophes when they help eliminate confusion, which happens most often with single letters. Mind your p's and q's is the typical spelling, and we write that the word aardvark has 3 a's, not 3 as.

Dos and don'ts is an especially unusual exception. The apostrophe in the contraction doesn't seems to make people want to use an apostrophe to make do plural (do's and don'ts), but then to be consistent, you'd also have to use an apostrophe to make don't plural, which becomes downright ugly (do's and don't's).

Style guides and usage books don't agree.

  • The Chicago Manual of Style and others recommend dos and don'ts.
     
  • The Associated Press and others recommend do's and don'ts.
     
  • Eats, Shoots & Leaves recommends do's and don't's.

What Should You Do? Unless your editor wishes otherwise, if you write books, spell it dos and don'ts; and if you write for newspapers, magazines, or the Web, spell it do's and don'ts. If you're writing for yourself, spell it any way you want. Just be consistent.

For more on using the apostrophe in plurals, see Erin Brenner's "Punctuation Point: The Apostrophe, Beyond the Basics."

I'm drawn to these tips and tricks like moths to a flame. They sure do ameliorate the learning process of the numerous nuances in Grammar and Punctuation.

This is the first time I've heard about you Grammar Girl (Mignon Fogarty), and after checking out the links provided, I find your presentation of the material to be learned fun, simple, yet still instructive and engaging enough to be an enjoyable experience.

I bookmarked the included links for cogitation and perusal and will be buying your book today on Amazon, "101 Words to Sound Smart", and am looking forward to learning from it even more fun and delectable words that I do here at Vocabulary.com!

I forgot to mention that I recently purchased, "The Blue Book of Grammar and Punctuation", a book referenced on Grammar Girl's links, finding it an efficacious and invaluable source for effective writing.

I'm not a writer of any sorts, but am fascinated by and eager to learn more about the prose of language, with my primary interest being attaining and learning more vocabulary words.

I liked your advise: "If you're writing for yourself, spell it any way you want. Just be consistent."

An important thing to remember is to know your readers. Write so they understand what you are saying. Don't use slang or expressions that are foreign to your readers. Don't try to use vocabulary that is not common to the intended readers. Use proper grammar and spelling, but don't try to be a perfectionist at the expense of the readers understanding.

Right on, Jeff...and more power to Rhonda H's Grammar Girl. (Note "H's" -- I would have gone with "ayches" prior to the lesson. Hmm, maybe.)

The reason I wouldn't use 'dos' now is because the word has something to do with computing. I am not sure what, but I know it used to mean something.

Besides that, seeing 'dos' without an apostrophe linked with 'don't' with one, looks awkward.

So I guess I'm one of the ones who will do it my own way. I'll try hard to be consistent.

When it comes to spelling, my now unsecret wish is for a letter to replace the schwa. Life would be less stressful! LOL
