Nine Obscure (but Useful) Recommendations from The Chicago Manual of Style

Reading The Chicago Manual of Style while on deadline is different from curling up with it for a leisurely read. If you haven’t had time for the latter, not to worry. I’ve compiled a list of lesser-known but useful recommendations from the sixteenth edition. [Update: Corresponding references for the 17th edition are in brackets.]



In informal writing, a comma need not follow an introductory yes or no: “Yes we can.”

  • CMS 6.39 [6.34]. In informal writing, a comma need not follow an introductory yes or no: “Yes we can.”
  • CMS 6.104 [6.106]. If one of the terms separated by a slash is an open compound, you can add a space before and after the slash to clarify word groups: exclamation point / period.
  • CMS 7.49 [7.53]. Only the first appearance of a non-English word needs to be italicized if, through repetition, readers will become familiar with it.
  • CMS 7.83 [7.87]. In compound modifiers where an adjective modifies an adjective-noun compound, the first hyphen is not necessary if the meaning is clear: late thirteenth-century music.
  • CMS 8.153 [8.154]. Proper nouns beginning with a lowercase letter followed by a capital—eBay, iTunes, iPhone—are considered capitalized and can begin a sentence or heading with the case of the initial letter intact. (Also see the In Style column “Lowercasing the First Word of a Sentence” in Copyediting’s August–September 2014 issue.)
  • CMS 8.163 [8.165]. Colons and commas omitted on title pages for design reasons should be added to the titles in running text, such as the colon between the title and the subtitle.
  • CMS 8.171 [8.173]. An italicized title used within an italicized title should remain italicized and be enclosed in quotation marks. Other italicized terms (e.g., non-English words, species names, ship names) used within a title should be set in roman.
  • CMS 8.196−7 [7.61–2]. Mottos and common short signs—such as Watch Your Step—are capitalized headline style but not italicized or enclosed in quote marks.
  • CMS 14.105 [14.96]. Though a colon usually separates the main title and the subtitle in running text, it does not follow a main title that ends with a question mark or exclamation point: Higglety Pigglety Pop! Or, There Must Be More to Life.
Punctuating Style in CMOS 17: What’s New with Colons, Commas, Dashes, and Slashes

Punctuating Style in CMOS 17: What’s New with Colons, Commas, Dashes, and Slashes

Since breaking news of the 17th edition, out in September, The University of Chicago Press has revealed some major revisions to The Chicago Manual of Style. Among the previews: lowercasing internet, dropping the hyphen in email, adding alt text to the manual for accessibility, improving keywords for searchability, expanding source citations to cover social media, and accepting themself to refer to a singular antecedent (as in they bought themself a book on quotations). Punctuation guidelines have also undergone a few tweaks, and though not nearly as controversial as going from e-mail to email, the following updates introduce new rules or clarify old ones for added finesse and flexibility.


The following updates introduce new rules or clarify old ones for added finesse and flexibility.

Colons

  • When introducing a list or series, the words preceding the colon no longer need to be a grammatically complete sentence if the verb is understood: New: metadata, abstracts, and keywords.

Commas

  • Reword the sentence when the serial comma causes ambiguity. When the serial comma might be misread as framing an appositive, one solution is to repeat the conjunction: Instead of she drove her wife, the teacher, and her mother, use she drove her wife and the teacher and her mother.
  • Use a comma after “etc.,” “et al.,” and “and so forth” only if required by the surrounding text. Instead of setting these terms off with a pair of commas according to the previous recommendation, treat them as equivalent to the final element in a series: The editor donated a dozen outdated reference books (without removing dog-ears, pencil marks, sticky notes, etc. from the pages).
  • Capitalize the first word of a direct question not enclosed in quotation marks when it follows a comma. Another departure from previous editions, this guideline makes this category of question analogous to a direct quotation: He wondered, Should I track changes?
  • It’s not necessary to precede the adverbs “too” and “either” with a comma when used in the sense of “also” at the end of a sentence. They couldn’t make the deadline either. The printer was down too.
  • In correspondence, a greeting containing a direct address requires two punctuations: a comma in the direct address and a colon or comma after the greeting.

Welcome, readers: . . .
Hi, Laura, . . .

But in casual correspondence, the direct-address comma is often omitted.

Hi Erin, . . .

Em Dashes

  • In printed publications, break the line after an em dash, not before. But when another punctuation mark immediately follows the dash, like in this example, keep the elements together:

“I’m saving my edits before I—”
the student said as the computer froze.

En Dashes

  • In printed publications, break the line after an en dash, not before. But if it pushes a single character to the next line, such as part of a number range or a score, keep the elements together.
  • An en dash with a space before and after may be used instead of an em dash in running text. Primarily a British style, an en dash as em dash is preferred by many U.S. publishers and writers.

Slashes

  • In printed publications, break the line after a slash, not before. But if it pushes a single character to the next line (such as when it is part of a two-year span) or splits a fraction, keep the elements together. This new rule doesn’t apply to poetry line breaks (break before or after) or URLs (break before).

Multiple Punctuation Marks

  • Except in formal prose, a question mark can be combined with an exclamation point to “express excitement or disbelief.” Are we another step closer to adopting the interrobang?!
