Punctuation

Q. When writing technical documentation, some steps may require a warning or information of note with the step. In those instances, the information begins either with “Warning:” or “Note:” (respectively). If the word before the colon is bolded, should the colon also be bolded?

Q. Could CMOS weigh in on the proper placement of punctuation in relation to quotation marks when the quoted material is an abbreviation that will be used in the document? For example: This agreement is entered into between Corporation X and Agency Y, individually “Party,” and collectively, the “Parties.” The typical rules would suggest the above punctuation is correct, but the abbreviations are technically “party” and “parties” (not “party,” and “parties.”). Would these be exceptions?

Q. Does CMOS prefer a slash or parentheses to denote an alternative? For example, “on/off” vs. “on (off).”

Q. Should there be a space on either side of an ellipsis in the middle of a line when using the Unicode ellipsis rather than three spaced periods? Example: Should there be a … space … like this? I’ve read CMOS 13.50, which says that authors can use the ellipsis character in their manuscripts instead of spaced ellipses, “usually with a space on either side.” But several authors disagree with me as an editor. Most authors insist on no…spaces…like this. Several have them like this… with a space on the right side only, before the clause continues. Thank you for your help!

Q. Can an ellipsis be used instead of a period at the end of a complete sentence?

Q. In formal writing, it is always recommended not to use contractions. But what about the expression “what’s more”?

Q. I was horrified to see that you endorsed using an apostrophe before the s to form plurals! “To aid comprehension, lowercase letters form the plural with an apostrophe and an s (compare ‘two as in llama’ with ‘two a’s in llama’)” (CMOS 7.15). I protest. An apostrophe conveys possession, or a contraction. It should never be used in this context. Please advise where this misbegotten rule came from.

Q. When a question introduces a list, should you use a question mark or a colon? Or both?

Q. I edited a travel book for children, and I would love to know your response to this comment from an Amazon reviewer: “U.S. is spelled US throughout the book; D.C. is also spelled without the accurate punctuation. That sort of inattention to accuracy is inexcusable.” The author has asked me to write a response to this for Amazon. This reviewer seems to think Chicago style is teaching kids bad punctuation habits. Thanks for your help.

Q. What’s the official CMOS stance on double question marks?? I see this a lot in blogs, online magazines, DIY news sites, etc.
